Ik it’s a lot and srry but can somebody answer 15,16 and 17?

16. x = 16

17. x = 11

Step-by-step explanation

15.

a. 58* Angle 2 = Angle 4 Angle 1 + Angle 2 = 180*

b. 58* Angle 3 + Angle 4 = 180*

c. 58* Angle 1 = Angle 6

d. 58* Angle 6 = Angle 8

e. 122* Angle 4 = Angle 2

f. 122* Angle 4 = Angle 5

g. 122* Angle 5 = Angle 7

16. Alternate Interior angles. They're equal.

10x - 29 = 8x + 3

2x = 32

Divide by 2 to isolate x

x = 16

double check by putting 16 in for x to see if original statement is true

10 (16) - 29 = 8 (16) + 3

160 - 29 = 128 +3

131 = 131

17. Consecutive interior angles. They equal 180*

13x - 26 + 5x + 8 = 180

18x - 18 = 180

18x = 198

Divide by 18 to isolate x

x = 11

Double check

13 (11) - 26 + 5 (11) + 8 = 180

143 - 26 + 55 + 8 = 180

180 = 180

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1
