Trigonometry
Objective: Use trigonometry functions to find the area of triangles.
In an isosceles Δ, the two equal sides each measure 14 meters, and they include an angle of 44*. Find the area of the isosceles triangle, to the nearest square meter.

Answer 1

The area of triangle is 68m²

Explanation:

`(1)/(2) ab \sin(c)`

Given that the formula to find the area of triangle is shown above. Then you can just substitute the following value into the formula :

Let,

a = 14m

b = 14m

c = 44°

A = 1/2 × 14 × 14 × sin 44°

= 68m²
