Triangle SAA

The triangle has one side long 71 m and its two internal angles is 60°. Calculate the perimeter and area of the triangle.

Correct answer:

p =  213 m
A =  2182.82 m²

Step-by-step explanation:

$p=3\cdot 71=213m$

$A={\displaystyle \frac{71^2}{2}}\sin ({\displaystyle \frac{\pi }{3}})=2182.82{\text{m}}^2$
