Question

Find the area of the triangle below.

Carry your intermediate computations to at least four decimal places. Round your answer to the nearest hundredth.

Answer 1

15.43 km^2

Explanation:

If base of triangle is 8 km, then height will be the line from vertex which is perpendicular with base

sin(40) = height/6

0.64278761 = height/6

height = 0.64278761 x 6 = 3.85672566

then area = 1/2 (3.85672566 x 8) = 15.42690264 or 15.43
