Question

Find the unknown marked angles in each of the following figures. Plz give correct answer in step by step answer with explanation in paper.....plz

Answer 1

Answer:

a=50(vertixally opposite angle)

b=50( parallel sides give complementary angle

c= 130(exterior opposite angle)

Answer 2

Answer:

CD || AB and EH is transversal.

therefore,

angle EFD = angle CFG (vertically opposite angles)

a = 50°

angle a = angle b. (alternate angles)

b = 50°

angle c + angle b = 180°. ( linear pair)

angle c = 180° - b

c = 180 - 50

c = 130°
