Answer:
x = 8
Step-by-step explanation:
First you have to find what x equals
To do that find all the angles inside triangle VWU
We can find angle U by subtracting 180- 86
= 94
SO now add up the variables from inside the triangle
x + 8 + 94 + 9x - 2 = 180
Add up like terms
10x + 100 = 180
Isolate 10x
10x + 100-100 = 180-100
10x = 80
Divide 10 in each side
x= 8
We already know the x so just put it in the angle
9(8) - 2
72 - 2
=70
To make sure it is correct find all the angles and add them all together to make sure it adds up to 180
70 + 94 + (8+8)
=180
