Question

Hey anyone think they can help me with this makeup work I was really sick for a while and I am just getting back into math please help

Answer 1

11) The angle relationship is 'Linear Pair' (supplementary)

2x + 7 + 6x + 5 = 180°

= 8x + 12 = 180

= 8x = 168

= x = 21

12) Vertical angles are congruent.

5x + 4 = 79

5x = 75

x = 15

13) Complementary angles add up to 90 degrees.

3x + 2 + x + 16 = 90°

4x + 18 = 90

4x = 72

x = 18

(substitute to check your answer! ^^)
