Question

Can someone help me out on this one

Answer 1

Explanation:

13.(3x+10)°=70°(becose they are alterneting angles which are equal to one an

other)

3x+10=70

3x+10-10=70-10

3x=60

3x/3=60/3(divid 3 both sided)

x=20

Answer 2

They are all equal to each other
13. 3x + 10 = 70
60= 3x
X = 20

14. 4x+3=103
4x= 100
X= 25

15. 8x= 120
120/8 = 15
