Question

Find the area of the triangle. triangle area 3A. 3.9 ft²B. 0.2 ft²C. 7 ft²D. 14 ft²

Answer 1

Applying the law of sines

The area of the triangle is given by the formula

`A=(1)/(2)(a)(b)sinC`

where

a=7 ft

b=2 ft

C=88 degrees

substitute

`\begin{gathered} A=(1)/(2)(7)(2)s\imaginaryI n88^o \\ \\ A=7\text{ ft}^2 \end{gathered}`

The answer is option C
