Answer:
-7,3
Step-by-step explanation:
The two unknown sides are equal to each other so then the two unknown angles are also equal.
A triangle angles add up to 180
36 + 2x = 180
2x = 180 - 36
2x = 144
unknown angles x = 72°
draw line down center of triangle to make two right triangles with side 22/2 = 11. SOH CAH TOA
cos(72) = 11/H
H = 11/cos(72)
H = 35.6
perimeter = 22 + 2(35.6)
perimeter = 93.2 cm
answer E .
You said that 'A is 30' right there in the equation
so it would be
Xsquared=30
Hey there!
In this scenario, we are given the area of the rug. It is asking for the diameter, the distance across the rug. The area is the radius (half of diameter) squared times pi (we will use 3.14).
First, we need to undo the area and find the radius.
78.5/3.14=25
√25=5
Since the diameter is twice the radius, we multiply or radius by two.
5*2=10
Therefore, our edge is 10 feet from one edge to the other.
I hope this helps!
