Question

A painter is going to apply a special coating to a triangular metal plate on a new building. Two sides

Answer 1

Answer:

$Area = 90.03cm^2$

Step-by-step explanation:

Given

$s_1 = 14.9$

$s_2 = 14.7$

$\theta = 124$ --- angle in between

Required

The area of the plate

Since $\theta = 124$ is between $s_1$ and $s_2$

The area is:

$Area = \frac{1}{2} * s_1 * s_2 * \sin(\theta)$

$Area = \frac{1}{2} * 14.9 * 14.7 * \sin(124.7)$

$Area = \frac{1}{2} * 14.9 * 14.7 * 0.8221$

$Area = 90.03cm^2$
