Question

Find the measures of angles a,b,c,d in the following figure:​

Answer 1

Step-by-step explanation:

45° + 25° + A = 180° ( angle sum property of triangle)

70° + A = 180°

A= 180 - 70°

A= 110°

b = A ( opposite angles )

b = 110°

D = 45° ( alternate angles )

110° + 45° + c = 180°

155°+ c = 180°

c = 180° - 155°

c = 25°
