Answer:
b) 94
Step-by-step explanation:
The Total Degree of a Triangle is 180 degrees. Knowing this, set up an equation.
68+26+x=180.
x is the complementary angle of the "?" angle.
Solve the equation.
94+x=180
x=86
Then Subtract 86 from 180 to find "?"
180-86=94
I hope this helps!
Answer:
94;b
Step-by-step explanation:
68+26=94. 180-94=86. 180-86=94.

The missing side is 53.6 units for the given right triangle.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
The right triangle is given in the question, as shown.
The ratio of the length of the side opposite the angle to the length of the hypotenuse of the triangle. The sine function is denoted by the symbol "sin" and is defined as follows:
sin(θ) = opposite / hypotenuse
Here, θ = 66°
Using the sine ratio in the given triangle, we get
sin 66° = perdenicular/hypertanuas
Substitute the known values in the above ratio,
sin 66° = 49/x
x = 49/sin 66°
x = 53.63717
Rounded to the nearest tenth,
x ≈ 53.6
Thus, the missing side is 53.6 units for the given right triangle.

Which of the following is an example of rigid transformations?
A. Moving the glass from one place to other
B. Cutting a piece of bread
C. Squeezing the cherry
D. All of the choices
Answer:
Moving the glass from one place to other is rigid transformation.
Step-by-step explanation:
The rigid transformation includes rotation, translation, reflection or their combination.
So, Moving the glass from one place to other place is translation. It is example of rigid transformation.
Now, cutting a piece of bread is not rotation or translation or reflection. So, it is NOT rigid transformation.
Squeezing the cherry is not rotation or translation or reflection. So, it is too NOT rigid transformation.
It is given 5 and h + 1 are the roots of the quadratic equation x² + (k - 1)x - 5 = 0,where h and k are constant.Find the value of h and k.
Do help me,i'll mark u as the brainliiest!!
Answer:
h=-2
k=-3
Step-by-step explanation:
in ax²+bx+c=0
sum of roots=-b/a
product of roots=c/a
sum of roots=5+h+1=h+6
product of roots=5(h+1)
so h+6=-(k-1)/1
so h+6=-k+1
h+k=1-6
h+k=-5
and 5(h+1)=-5/1
5(h+1)=-5
h+1=-5/5=-1
h=-1-1=-2

Answer:
Relative to such interrogate proposed, the answer is identified as 5520, if quantities ‘a’ and ‘b’ were to subject to define, given such conditions.
Step-by-step explanation:
Understood:
- Such quantity is a four (4) digit number, as explicitly stated.
- The value must be divisible by three (3). Thus, once the digits are summed, such quantity must be able to divide, and distribute evenly, into three (3).
- Likewise, such number is obligated to be divisible by five (5). Thus, the last digit of such quantity must end in either a ‘5’ or a ‘0’.
We were given the mathematical expression: 5a2b
5 + 2 = 7 + x = a number that is divisible by three, as stated in the problem.
X could be a list of differentiated number(s), although for a simplicity, x could be equated to as 5 to produce 12 (which is a factor of three, hence, divisible by three).
Now that ‘a’ has been substituted, ‘b’ must be substituted, similarly:
With ‘b’, we could appoint any number, so long that is either a 5 or 0 in the last digit, hence producing a value divisible my five.
For simplicity, which choosing either 5 or 0 does not make a difference, I will choose zero.
Thus, the rectified answer to such an interrogate is 5520. The difference between the largest of such number and the smallest is their abilities to become divisible by a certain constant ‘a’ and ‘b’.

Step-by-step explanation:
we want to simplify the following expression:

remove parentheses and change its sign because we know that two negatives make positive Thus:
[tex] \displaystyle 13 + 18[/tex]

in a set of 3 numbers the first is a positive integer, the second is 3 more than the first and the 3rd is a square of the second
a) the first number in the set is x. write the second and third numbers in terms of x
b) the sum of the numbers is 77
c) write down an equation in terms of x
d) show that your equation simplifies to x²+8x-65=0
Given:
In a set of 3 numbers the first is a positive integer, the second is 3 more than the first and the 3rd is a square of the second.
To find:
The equation for the given situation if the sum of the numbers is 77.
Solution:
a. Let the first number in the set is x.
The second is 3 more than the first. So, the second number is [tex](x+3)[/tex].
The 3rd number is a square of the second. So, the third number is [tex](x+3)^2[/tex].
Therefore, the first, second and third numbers are [tex]x,(x+3),(x+3)^2[/tex] respectively.
b. The sum of the numbers is 77.
First number + Second number + Third number = 77
c. So, the equation in terms of x is:
[tex]x+(x+3)+(x+3)^2=77[/tex]
Therefore, the required equation is [tex]x+(x+3)+(x+3)^2=77[/tex].
d. On simplification, we get
[tex]x+x+3+x^2+6x+9=77[/tex] [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]
[tex]x^2+(6x+x+x)+(3+9)=77[/tex]
[tex]x^2+8x+12=77[/tex]
Subtract 77 from both sides.
[tex]x^2+8x+12-77=77-77[/tex]
[tex]x^2+8x-65=0[/tex]
Therefore, the simplified form of the required equation is [tex]x^2+8x-65=0[/tex].

If 12 is the greatest common factor of y and 36, how many possible values for y are in between 20 and 80 ?
Answer: 3
Step-by-step explanation: I don’t have an explanation but I got the same question on a quiz and 3 was the correct answer.
the possible values for y are in between 20 and 80 will be 3.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
If 12 is the greatest common factor of y and 36.
The value of y will be a multiple of 12 and greater than 36.
Then the numbers will be
12 x 4 = 48
12 x 5 = 60
12 x 6 = 72
Then the possible values for y are in between 20 and 80 will be 3.

The robotics team purchased 3 androids for the purpose of programming. Each of the robots was $398, which included tax. If the tax rate is 8%, what is the TOTAL TAX to be paid?
Answer:
$95.52
Step-by-step explanation:
Number of robots = 3
Cost of each robots = $398
Tax rate = 8%
Amount of tax of each robots = 8% of $398
= 8/100 × $398
= 0.08 × $398
= $31.84
TOTAL TAX to be paid = Amount of tax of each robots × Number of robots
= $31.84 × 3
= $95.52
TOTAL TAX to be paid = $95.52
