cos 48 = 30/x
x cos 48 = 30
x = 30 / cos 48
x=44.83429
Rounding to the nearest tenth

The area of a triangle is one-half times the base times the height. If the area of a
triangle is 54 sq. in, and its height is 12 in., what is the base????
I rlly need answer haha
Answer:
The base is 90 sq
Step-by-step explanation:
Formula for Area= 1/2*b*h
where b is unknown and area = 54sq
Placing in formula1/2 *b*12 = 54sq
12b = 54*2
12b /12 = 54*2/12
b = 9sq

O 5x + 3y = 18
O 5x - 3y = 30
O 5x - y = 30
O 5x + y = 18
Answer:
Hello the answer is 5x - y = 30!
Step-by-step explanation:
m = (0 (-5))/(6 - 3) = (0 + 5)/(3) = 5/3
y = mx + b
O = (5/3)(6) + b
O = (30/3) + b
O = 10 + b
-10 = b
3y = 5x - 30
3y + 30 = 5x
5x - 3y = 30

Which parabola(s) have an axis of symmetry of x = -1
Answer:
b,c
Step-by-step explanation:
The axis of symmetry is along the vertex
a has a vertex at x=1
b has a vertex at x = -1
c has a vertex at x=-1
d has a vertex at x =2
Explanation:
Notice how the vertical line through the center of these parabolas is at x = -1. In other words, the vertical line cuts through -1 on the x axis. Reflecting one half of the parabola over this line will result in the other half.

a triangle with 2 equal sides is called
Answer:
isosceles triangle.
Step-by-step explanation:
Answer:
Isosceles triangle
Step-by-step explanation:
In isosceles triangle, two sides are equal and the angles opposite to these equal angles are also equal. The third side of the triangle is called base
Please help……………………….
Let’s start with the easy part: half of the base is 3.
Therefore, 3 x h + 1 = 18
3 x h = 3h and 3 x 1 = 3
3h + 3 = 18
To solve these equations, you have to do the inverse. First you would need to minus 3:
3h = 15
3h is a simpler way of saying 3 x h, so the inverse would be a divide.
h = 5
Given the following information, give as complete a description of this figure as possible, including the measure of any sides and angles and any terms that can be used to describe the polygon.
Answer:
It's a square with four equal sides each side is 6cm. The angles at the four edges are all same have 90° between each two sides. You can calculate the area of the four triangles by using the formula 1/2 × hight × base. The hight will be 6 divided by 2 which is equal 3cm, and the base will be 6cm. So the area of each triangle is 1/2×3×6=9cm^2.
A triangle has an area of 10 square feet. The height is 10 feet. What is the length of the base (in feet)?
Answer:
2 feet
Step-by-step explanation:
for area of a triangle it's (height times width) divided by 2, and 10 times 2 divided by 2 is 10
Answer:
Length of base of triangle = 2 feet
Step-by-step explanation:
Given:
Area of triangle = 10 square feet
Height of triangle = 10 feet
FInd
Length of base of triangle
Computation:
⇒ Area of triangle = (1/2)(Base)(Height)
⇒ 10 = (1/2)(Base)(10)
⇒ 10 = Base(5)
⇒ Length of base of triangle = 10 / 5
Length of base of triangle = 2 feet

What is Number system?A number system is defined as a system of writing to express numbers.
Given that David has 4 cages of hamsters.
The second cage has 1/2 as many hamsters as the first.
The third cage has 1/2 as many hamsters as the second.
The fourth cage has 1/2 as many hamsters as the third.
Let the first cage has n number of hamsters
the first cage has n/2 number of hamsters
the second cage has n/4 number of hamsters
the third cage has n/8 number of hamsters
the third cage has n/16 number of hamsters
4=n+n/2+n/4+n/8+n/16
n=15
Hence, the fewest hamsters David can have are 15

find the midpoint between this pair of points (-4,10) and (14,0)
Explanation:
The x coordinates are -4 and 14. They add up to -4+14 = 10. Then this cuts in half to get 10/2 = 5. This is the x coordinate of the midpoint.
We'll follow this same idea for the y coordinates as well.
10+0 = 10 which cuts in half to 10/2 = 5, and this is the y coordinate of the midpoint.
Therefore, the midpoint is (5,5).
Coincidentally, the x and y coordinates are the same for the midpoint (both are 5). This won't always happen.

S is the centroid of the triangle. Find IT if ST =9
Answer:
27
Step-by-step explanation:
The centroid divide a median in two parts, with ratio 1/3 and 2/3.
In particular the part between the centroid and the point where the median touches the side is 1/3 of the median.
We can build this proportion:
ST : 1/3 = IT : 3/3
9 : 1/3 = IT : 1
IT = 9 * 3 = 27
The diagram shows a square with side length 5cm.
The length of the diagonal is y cm.
Find the exact value of y.
Answer:
5sqrt2
Step-by-step explanation:
Using the pythagorean theorem, we get 5^2+5^2=c^2. C is the diagonal here. 25+25=c^2, c^2=50. c=sqrt50. Simplifying it, we get the diagonal as 5sqrt2.
