Answer:
Step-by-step explanation:
perimeter P= 2L+2W
360=2(L+W) divide by 2
180=L+W
we know the L=100
180=100+W
W=80
Answer:
16.2
Step-by-step explanation:
A trick to remember for right triangles is SOH-CAH-TOA:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we have the side adjacent to the angle and the hypotenuse. So we should use cosine.
cos 22° = 15 / x
x = 15 / cos 22°
x ≈ 16.2
Answer:
