Two angles are supplementary if the sum of their measures is 180 degrees. the measure of the first angle is 18 degrees less than two times the second angle. find the measure of each angle

66 and 114

Step-by-step explanation:

y+x=180

y=2x-18

now substitute

2x-18+x=180

3x=198

x=66

now we can also solver for y

66+y=180

y=114

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
