Question

15x+10 80
I need help plzzzzzzz

Answer 1

explanation:

they’re supplementary angles (they add up to 180°), so we need to set up an equation by adding them to equal 180°:

15x + 10 + 80 = 180

combine like terms

15x +90 = 180

subtract 90 from move sides

15x = 90

divide both sides by 15

x= 6

Answer 2

6

Explanation:

180-80=100

100-10=90

90 divided by 15=6
