1) 25

2) 155

3) 25

4) 25

5) 19

7)

CODE:

Step-by-step explanation:

1) 180 - 155 = 25

2) 155 = angle 4

3) angle 1 and 5 are equal = 25

4) angle 1 and 7 are equal = 25

5) 19

5x + 15 = 8x - 42

5x + 15 - 5x = 15

8x - 42 - 5x = 3x - 42

15 + 42 = 57

3x - 42 + 42 = 3x

57 = 3x

57 / 3 = 19

3x / 3 = x

19 = x
