Answer:
140° and 50°
Step-by-step explanation:
The supplement of the angle (180 - x)
The complement of the angle = (90 - x)
(180 -x) = 4(90-x) - 60
180 - x = 360 -4x - 60
180 -x = 300 - 4x
180 - x + 4x = 300
180 + 3x = 300
3x = 120
x = 40
The supplement (180 - x) = 180 - 40 = 140°
The complement (90 - x) = 90 - 40 = 50°
To isolate the variable you would divide both sides of the equation by 3, resulting in the equation to answer c = 4/3 or c = 1.3
48 because 9x=54. 54 divide by 9 is 6. 6 times 8 is 48
