y² = 8y - 15 (alternate angles are equal)
y² - 8y + 15 = 0
(y - 5)(y - 3) = 0
y = 5 or 3
x + 8y - 15 = 180 (angles in a straight line add up to 180)
when y = 5
x + 40 - 15 = 180
x = 155°
when y = 3
x + 24 - 15 = 180
x = 171°
I got the answer isa D mate
Please lord thank you lord lord
X = 140
You do 110 + 30 and that gives you 140. Hope it helped!
Start by subtracting r, then divide -N That equals out to C = RN - PN , It's a bit Confusing lol<span />
