Question

How do you find the area of a triangleABC, if `angleC = 62^@`, `b = 23.9` , and `a = 31.6`?

Answer 1

`color(brown)("Area of triangle ") color(green)(A_t = 333.42) color(purple)(" sq units"`

Explanation:

`"Given : a = 31.6, b = 23.9, hat C = 62^@`

Applying the formula `A_t = (1/2) a b sin C, color(brown)(" using 2 sides and the included angle"`

`A_t = (1/2) * 31.6 * 23.9 * sin 62 = 333.42 " sq units"`
