one angle is twice the other angles.if these angles are complementary,find two angles

two angles are complementary if they add up to 90 degrees

let the angles be x and y

one angle is twice the other angle

x = 2y

x and y are complementary

x + y = 90

by solving the system of equations

x = 2y

x + y = 90

we find

x = 60 degrees

y = 30 degrees

the two angles are 30 and 60 degrees.

Complementary angles total 90-degrees.

Let's divide both sides by 3...

Complementary angles mean that the two angles, when added together, equal 90°.

Let's call the first angle x, and its second, complementary angle 2x.  So, we have x + 2x = 90.

Solving for x, we get x = 30.

Since the first angle was called x, that means it's measurement is 30°.  The second angle, 2x, is just twice the first angle, so its measurement is 60°.
