Question

please solve the question step by step in a copy with solution.

Answer 1

see did the solution the answer is a=87°,b=87°,c=45°,d=48°

Answer 2

hi friend

your answer is :

angle A + angle B + angle a = 180° ( angle sum property )

48° + 45° + angle a = 180°

93 + angle a = 180°

angle a = 180° - 93°

angle a    = 87°

angle B = angle c ( alternate interior angles )

angle B = 45°

angle c = 45°

angle A = angle d

angle A = 48°

angle d = 48°
