16.5 is what I got for x you add them up and equal them to 180 because its a straight line
Answer:
x = -1
Step-by-step explanation:
5x + 5 = 0
Subtract 5 from each side
5x+5-5 = 0-5
5x = -5
Divide by 5 on each side
5x/5 = -5/5
x = -1
The sum of the angles equals 540
There are 3 angles that measure (x - 30) and 2 angles that measure (x)
3(x - 30) + 2(x) = 540
3x - 90 + 2x = 540
5x - 90 = 540
5x = 630
x = 126
x - 30 = 126 - 30 = 96
Answer: x = 126, x-30 = 96
