Answer:
A= 115 degrees
C= 50 degrees
Step-by-step explanation:
All angles are equal to 180 so the equation is:
180=4x-13+x+18+15
180=5x+20
160=5x
x=32
Answer: x = 32 because 4 times 32 = 128 and 128 - 13 = 115 and 115 + 15 = 130 and 32 + 18 = 50 and 130 + 50 = 180. the angle for A is 115 and the angle for C is 50. Hope it Helps.
