Question

Find m abc (2x) (5x+5)

Answer 1

< ABD + > ABC = 180.....because these angles form a linear pair
2x + 5x + 5 = 180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175/7
x = 25

< ABC = 5x + 5......5(25) + 5 = 130 <==

Answer 2

(2x) (5x+5) = 180

7x + 5 = 180

7x = 175

x = 25

5(25) + 5 = 125 + 5 = 130

130 is your answer

hope this helps
