Answer: 124 degrees
Step-by-step explanation: We know that in all quadrilaterals the total degrees of the angles will = 360 so we simply add up all the angles given in the picture and get 9x-27=360. Divide by 9 and x-3=40, add 3 to both sides and you find x = 43. You’re not don’t though, you need to plug that number back into the equation 3x-5=theta and you get 124.
