Question

X, Y and Z form the vertices of a triangle, where

∠
YXZ = 62°, XY = 6.1m and XZ = 7.9m.
Calculate the area of the triangle. Round your answer to 1 DP.

Answer 1

Explanation:

When sides 'z' and 'y' and included angle X is known, the area of the triangle is:

Area (∆XYZ) = 1/2 × yz × sin(X)

1/2 x 7.9 x 6.1 x Sin(62) = 21.27
