Find the value of x. m<1=7x-3 and m<2=5x+9 x=_____ m<1=_____ m<2=_____ 13. Find the value of x. m<3=8x+7...
x=_____
m<1=_____
m<2=_____
13. Find the value of x. m<3=8x+7 and m<4=12x-9
x=_____
m<3=_____
m<4=_____
12. To find the value of x, set m<1 equal to m<2 because they are vertical angles:
7x - 3 = 5x + 9
2x = 12
x = 6
m<1 = 7(6) - 3 = 42 - 3 = 39
m<2 = 5(6) + 9 = 30 + 9 = 39
13. To find the value of x, set m<3 equal to m<4 because they are vertical angles:
8x + 7 = 12x - 9
4x = 16
x = 4
m<3 = 8(4) + 7 = 32 + 7 = 39
m<4 = 12(4) - 9 = 48 - 9 = 39
