Find the value for x that makes m
ll n?
m
n
(3x + 47)°
(x + 7)
x 7

Answer 1

x = 31.5

Explanation:

(3x + 47)° + (x + 7)° = 180° (same side interior angles theorem)

`3x + 47 + x + 7 = 180`

Collect like terms

`4x + 54 = 180`

Subtract 54 from both sides

`4x = 180 - 54`

`4x = 126`

Divide both sides by 4

`x = (126)/(4)`

`x = 31.5`
