Question

In triangle side BC of a triangle ABC has been produced to a point D. If angle ACD=115° and angle A=45°,then angle B is what?

Answer 1

Step-by-step explanation:

angle A is 45°

angle ACD is 115°

angle ACD + angle ACB = 180° ( ACD is straight lin)

115°+ angle ACB = 180°

angle ACB =180°-115°

angle ACB = 65°

In ∆ ABC,

angle A + angle B + angle C =180°

45°+angle B+65°=180°

angle B +110°=180°

angle B=180°-110°

angle B=70°
