Perimeter of triangle

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

Correct result:

o =  70.9808 cm


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