I would say the equation would be 3x=x+20 and subtract x on both sides and you get 2x=20 so then you would divide both sides by 2 and the answer is 10.

Actually welcome to the concept of the Angle sum property...

The Angle sum property of a Quadilatetal =》

m/_A + m/_B + m/_C + m/_ D = 360°

Thus adding all the angles we get as....

=》 X + X + X+ 15° + X + 45° = 360°

=》 4X + 60° = 360°

thus ..4X = 360 - 60 = 300

Thus .. 4X = 300

X = 300 ÷ 4 =》 75°

X = 75°
