Answer:
x = 13
Step-by-step explanation:
Supplementary means 180 degrees.
Since we are finding the supplement, we are going to add both angles together and solve for x.
3x + 11 + 17x - 91 = 180
~Combine like terms
20x - 80 = 180
~Add 80 to both sides
20x = 260
~Divide 20 to both sides
x = 13
Best of Luck!
Answer:
Since the measure of both angles are supplementary, its easy to form the equation.
3x+11+17x-91 = 180
20x-80 = 180
20x = 100
x = 5
m<a = 3x+11
= 3(5)+11
= 15+11
= 26
m<b = 17x-91
= 17(5)-91
= 85-91
= -6
