Jan 04, 12:41:42 AM The measures of the angles of a triangle are shown in the figure below. Solve for x
75°
63°

x = 20

Step-by-step 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

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
