Answer:
<em>71°</em>
Step-by-step explanation:
The angle of x and angle of 109, are supplementary, which means when added they are equal to 180 degrees.
109 + x = 180
x = 180 - 109
x = 71
Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.
All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40
c=-5
2c-3=12-2c+7c
2c-3=12+5c
2c-5c-3=12
-3c-3=12
-3c=12+3
-3c=15
c=15/-3
165 i think
blah blah blah blah blah
