Answer:
a. (5x+75)°
b. x = 21
c. X° = 21° and (4x+75)°= 159°
Step-by-step explanation:
A. Combine like integers.
B. (5x+75)°=180° Because they are suplementary angles.
5x°= 105°
5x ÷5 = 105 ÷ 5
x = 21
C. (4x + 75)°
4(21) + 75
84 + 75 = 159°

Step-by-step explanation:
All of the following are true except:
B = A, B, C are coplanar.
(I believe this should be the answer, but I'm not so sure.)
The answer is x=6.1 i believe
It's 85 degrees. Hope this helps
