What is the area of this triangle?
Round only your final answer to the nearest hundredth.

Answer 1

Area = 91.3471875

Explanation:

Area = ½ • side 1 • sine (A) • side 2

Area = (1/2) * 15 * sine(77) * 12.5

Area = 7.5 * 0.97437 * 12.5

Answer 2

We'll use the side angle side area formula:
Area = ½ • side 1 • sine (A) • side 2
Area = (1/2) * 15 * sine(77) * 12.5
Area = 7.5 * 0.97437 * 12.5
Area = 91.3471875
