Perimeter of triangle

In the triangle, ABC angle A is 60° angle B is 90°, and side size c is 15 cm. Calculate the triangle circumference.

Correct answer:

o =  70.9808 cm

Step-by-step explanation:

c=15 cm A=60 B=90 C=180AB=1806090=30 a=c tanA=c tan60 =15 tan60 =15 1.732051=25.98076 cm b=a2+c2=25.98082+152=30 cm o=a+b+c=25.9808+30+15=70.9808 cm
