In ΔOPQ, q = 110 inches, o = 970 inches and ∠P=167°. Find the area of ΔOPQ, to the nearest square inch.

ki77a [65]

Answer:

$Area = 12004$ square inches

Step-by-step explanation:

Given

$q = 110$

$o = 970$

$\angle P =167$

Required

The area of the triangle

To do this, we use:

$Area = \frac{1}{2} * o * q * sin(P)$

So, we have:

$Area = \frac{1}{2} * 970 * 110 * sin(167^\circ)$

$Area = \frac{1}{2} * 970 * 110 * 0.2250$

$Area = 12003.75$

Approximate

$Area = 12004$
