XY and AB intercect at point C. If angle XCB = 4x - 9 and angle ACY = 3x + 29 find angle XCB (I feel like this is easy but I'm missing the formula lol)

Ping me please

coarse horizon Ping me please

Vertically opposite angles are equal

#

So 3x+29 = 4x-9

So 38?

#

x would be 38

#

but then you need the angle so just sub 38 back into one of them

#

So 180 - 38 = XCB right?

#

Never mind got it

Thank you
