Answer:
gonna guess you're asked to find the measures of two interior angles given at least one exterior angle and one interior angle.
Two angles on the same line are SUPPLEMENTARY. Let's say your exterior angle is 95 degrees. That makes the corresponding interior angle 180 - 95 = 85 degrees. If your other interior angle is 79 degrees, then your last interior angle is 180 - (85 + 79) = 16 degrees.
The measure of x and y is -
x = 40°
y = 50°
We have a figure shown in the image.
We have to determine the measure of angle x and angle y.
What is the relation between the sides of any triangle ?The relation states that the sum of the any two sides of a triangle is always greater than the third side. Mathematically -
a + b > c
According to the question -
y + (2x + 50)° = 180° [supplementary angles have a sum of 180°]
2x + y = 130°
y = 130° - 2x
Therefore, in the right - angled triangle -
x + 130° - 2x + 90° = 180° [the sum of angles of a Δ = 180°]
- x + 220° = 180°
x = 220° - 180°
x = 40°
and
y = 130 - 2 x 40 = 50°
Hence, the measure of x and y is -
x = 40°
y = 50°

Find the angle of depression
from point A to point C.
?
66°
5 mi
B
Angle of depression = [ ? ]
Given:
In triangle ABC, [tex]m\angle A=66^\circ, AB=5\text{ mi}[/tex].
To find:
The angle of depression from point A to point C.
Solution:
According to angle sum property, the sum of all interior angles of a triangle is 180 degrees.
In triangle ABC,
[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]
[tex]66^\circ+90^\circ+m\angle C=180^\circ[/tex]
[tex]156^\circ+m\angle C=180^\circ[/tex]
[tex]m\angle C=180^\circ-156^\circ[/tex]
[tex]m\angle C=24^\circ[/tex]
We know that if a transversal line intersect the two parallel lines, then alternate interior angles are equal. So, the angle of depression from point A to point C is equal to the measure of angle C in triangle ABC.
Therefore, the angle of depression is 24 degrees.
What is 25% of 24?
What is 15% of 60?
9 is what percent of 72
Answer:
6
9
6.48
Step-by-step explanation:
this is the easiest way to solve for percentage:
[tex]\frac{part}{whole} =\frac{part}{whole}[/tex] Where all the percents (except 100) would go in part
and the whole number would go in whole
[tex]\frac{25}{100} =\frac{?}{24}[/tex] Then multiply 24 × 25 ÷ 100 = 6
[tex]\frac{15}{100} =\frac{?}{60}[/tex] Multiply 60 by 25 then divided by 100 = 9
Then for the last one 9 is what percent of 72
all we have to do is multiply 9 and then convert 72 into a decimal (0.72)
Then 9 × 0.72 = 6.48
Answer:
6.48

Write your answer in decimal form, rounded to the nearest thousandth.
Submit Question
Answer:
we got 10 digits to choose from for the first digit, 9 for the second and so on
[tex]10 \times 9 \times 8 \times 7 \times 6 \times 5[/tex]
scenarios that got no repeated digits.
the total number of possible PINs with 6 digits is
[tex]10 \times 10 \times 10 \times 10 \times 10 \times 10[/tex]
or just 10⁶
so the fraction we are looking for is the number of valid states decided by all possible states.
[tex] \frac{10 \times 9 \times 8 \times 7 \times 6 \times 5}{ {10}^{6} } [/tex]
=0.1512
rounded to the nearest thousandth it's

Two vertical angles measure (5x + 15)° and (3x + 27)°. Draw a diagram that illustrates the vertical angles. Solve for each angle.
Answers:
x = 6
Each angle is 45 degrees
The diagram is shown below
=========================================================
Explanation:
Vertical angles are always congruent
Set the two expressions equal to each other and solve for x.
5x+15 = 3x+27
5x-3x = 27-15
2x = 12
x = 12/2
x = 6
As a way to check the answer, replace x with 6 in each expression. We should get the same thing on both sides
5x+15 = 3x+27
5*6+15 = 3*6+27
30+15 = 18+27
45 = 45
Each angle is 45 degrees, so the answer is confirmed.
---------
The diagram is shown below. There are infinitely many ways to draw out the diagram. In the version I drew, the angles aren't vertically aligned but instead they are opposite one another in this X configuration. So the vertical angles could be vertically aligned, but they don't have to be.
In short: draw an X shape and mark any two opposite angles to form the vertical angles.
What type of solutions does the quadratic equation, 8v2 + 8 = -11v, have?
Answer:
Complex roots
Step-by-step explanation:
Given
[tex]8v^2 + 8 = -11v[/tex]
Required
The type of solution
Rewrite as:
[tex]8v^2 +11v+ 8 = 0[/tex]
To determine the type of solution, we simply calculate the discriminant (D)
[tex]D = b^2 - 4ac[/tex]
Where
[tex]a = 8;\ \ \ b =11\ \ \ c = 8[/tex]
So, we have:
[tex]D = 11^2 - 4 * 8 * 8[/tex]
[tex]D = 121 - 256[/tex]
[tex]D = -135[/tex]
The above value implies that:
[tex]D<0[/tex]
When [tex]D<0[/tex], the solution of the equation is: complex roots

Answer:
a) 2π radians
b) 10π inches
c) 5/4π inches per minute
Step-by-step explanation:
The formulas are fairly straightforward. Use the given values in each.
a) θ = ωt
θ = (π/4 radians/min)(8 min) = 2π radians
__
b) s = rθ
s = (5 in)(2π radians) = 10π in
__
c) v = s/t
v = (10π in)/(8 min) = 5/4π in/min
a water main is to be constructed with a 10% grade in the north direction and a 20% grade in the east direction. determine the angle theta required in the water main for the turn from north to east
Answer:
26.6degrees
Step-by-step explanation:
Given
percent grade through north = 10% (opposite)
percent grade through east = 20% (adjacent)
Get the direction
Using the SOH CAH TOA identity
tan theta = opp/adj
tan theta = 10/20
tan theta = 0.5
theta = arctan (0.5)
theta = 26.6degrees
Hence the required angle is 26.6degrees

Ida's ice-cream stand has increasing profits each week during the hot summer months. Ida finds that each week during the summer her profits increase by 15% over what they were the previous week. In her first week of business, her profits were $600. How much money will she make in all over 5 weeks?
Answer:
Ida makes $ 6960 in 5 weeks.
Step-by-step explanation:
Let the profit of the first week is p.
p = $ 600
Total profits of the five weeks
= p + (p + 0.15p) + (p + p +0.15 p) + (p + p + p + 0.15 p) + (p + p + p + p + 0.15 p)
= 11 p + 0.6 p
= 11 x 600 + 0.6 x 600
= 6600 + 360
= $ 6960
So, Ida makes $ 6960 in 5 weeks.

Answer:
Yes, it is:
Step-by-step explanation:
Given
