Question

in a triangle abc angle b is equal to 35 degree and Angle C equals to 55 degree write which of the following is to AC square equal to a b square + BC square A B square equal to BC square + AC square b square equal to a b square + AC square​

Answer 1

Step-by-step explanation:

BC is a triangle. <A = 52 deg, <B = 58 deg, so < C = 180–52–58 = 70 deg. AB or c = 20 cm

sin A/a = sin B/b = sin C/c, or

sin 52/a = sin 58/b = sin 70/20, or

a = 20xsin 52/ sin 70 = 16.77167057 cm

b = 20xsin 58/ sin 70 = 18.04947868 cm

So BC = 16.77167057 cm, AC = 18.04947868 cm and <C = 70 degrees.
