Triangle SAA

A triangle has one side of length 23 m and two interior angles of 60°. Calculate its perimeter and area.

Final Answer:

o =  69 m
S =  229.0637 m2

Step-by-step explanation:

a=23 m α=60  β=60  γ=180αβ=1806060=60   a=b=c  o = a+b+c  o=3 a=3 23=69 m
S=2a2 sinα=2a2 sin60° =2232 sin60° =2232 0.866025=229.064=229.0637 m2
