The acute angles of a triangle are complementary

Complementary angles are two angles that add up to 90 degrees. If angle C is a right angle, then it has a measure of 90 degrees. The angles in a triangle must sum to 180 degrees. If one angle is already 90 degrees, then the other two angles must sum to 90 degrees since 180- 90 = 90.

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)
