Question

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. A = 50°, b = 31 ft, c = 18 ft

Answer 1

use law of cosines a^2=b^2+c^2-2bccosA

Answer 2

To find the area, use the area formula which says Area - 1/2 the product of two adjacent sides times the sine of the included angle.

Answer 3

so we have
961+324-2*31*18*cos50

Answer 4

yeah i got that too
