The measures of the angles of a triangle are shown in the figure below. Solve for x
75°
63°

Answer 1

x = 20

Explanation:

The sum of angle of a triangle is 180. Taking the sum of the angles and equating to 180 will give:

75 + 63 + 4x+2 = 180

138+2+4x = 180

140+2x = 180

2x = 180=140

2x = 40

x = 20

Hence the value of x is 20
