Question

Help me with thisss please its timed!!! i need help

Answer 1

(2x+10)°+(4x+20)°= 180° ( linear pair)

2x+10+4x+20=180

=6x+30=180                     6x=180-30

6x=150

x= 150/6= 25

x=25

2x+10=50+10=60

4x+20=100+20=120

we can check if we did correct if the angles add up to 180 as they are a linear pair
