$69.64 I THINK IS HOW MUCH SHE WILL HAVE TO PAY.
HOPE THIS HELPS
Given:
side lengths of right triangles = 12 cm ; 16 cm ; 20 cm
lateral area = 192 cm²
lateral area of a triangular prism = perimeter * height
192 cm² = (12 cm + 16 cm + 20 cm) * height
192 cm² = 48 cm * height
192 cm² / 48 cm = height
4 cm = height
The height of the pedestal in the shape of a triangular prism is 4 cm.
Answer:
I think <2 = 37⁰
Step-by-step explanation:
if I remember correctly, if its straight across from it, it must be the same angle.
which means that 1 and 3 must have the same angle, and 2 must have the same angle as the other side, meaning its angle is 37⁰.
