Hey mate !!
Here's your answer !!
In a triangle the sum of all angles = 180
Angle 1 + Angle 2 + Angle 3 = 180 But we also know that sum of exterior angle of a triangle is equal to the sum of opposite interior angles. So, Angle 1 + Angle 2 = Angle 4 6x + 6 + 4x + 14 = 11x + 9 10x + 20 = 11x + 9 11x - 10x = 20 - 9 x = 11 So Angle 4 = 11x + 9 = 11(11) + 9 = 121 + 9 => 130 degrees Hence Angle 4 is 130 degrees. Hope my answer helped !! Cheers !!
