8) Find x if m m<br> i’m
Kaylis [27]

Answer:

7

Step-by-step explanation:

Remark

The two angles with x in their numerical value are added to get 108

Solution

10x + 2 + 4x + 8 = 108                Collect like terms

14x + 10 = 108                             Subtract l0 from both sides.

14x + 10 -10 = 108 - 10                Collect like terms

14x = 98                                      Divide by 14

x = 98/14

x = 7
