The two angles when added together need to equal 180 degrees:
-4x +5 + -13x +39 = 180
Simplify:
-17x + 44 = 180
Subtract 44 from each side:
-17x = 136
Divide both sides by -17:
x = 136 / -17
x = -8
Answer:
x=-4
Step-by-step explanation:
The angles have to equal eachother, so:
130=134+x
subract 134 from both sides
-4=x

Answer:
x = 10
z = 116°
Step-by-step explanation:
By the definition of supplementary angles, we have:
Step 1: Find <em>x</em>
7x + 46 + 5x + 14 = 180
12x + 60 = 180
12x = 120
x = 10
Step 2: Find the supplementary angle to <em>z</em>
5(10) + 14
50 + 14
64
Step 3: Find <em>z</em>
180 - 64 = 116
