Answer 2

Answer:

If AB||CD then

angle C = 60° ( alternate interior angles)

In triangle ODC

we have

angle D = 55°

angle C = 60°

angle O = ???

Sum of angle=180°

angle D + angle C + angle O = 180°

55°+60°+angle O = 180°

115°+angle O = 180°

angle O = 180°-115°

angle O = 65°

angle O = angle b ( opposite interior angles)

angle b = 65°

In triangle ABb

we have

angle B = 60°

angle b = 65°

angle A = ???

sum of angle=180°

angle B + angle b + angle A=180°

60°+65°+angle A=180°

125°+angle A=180°

angle A = 180°-125°

angle A = 55°
