how large is an angle whose supplement contains 12 degrees more than twice its complement?

let the angle be x

then its complement is 90-x

its supplement is 180-x

180-x = 12 + 2(90-x)
180-x = 12 + 180 - 2x
x = 12

the angle is 12°

check:
if angle is 12°, its complement is 78°
and its supplement is 168°

what is 12 more than twice 78 ?
2(78) + 12 = 168
which is the supplement !
Yeahhh!!!

To find the size of the angle, we need to solve the given equation. Let's denote the angle as "x."

The complement of an angle is the angle that, when added to the given angle, sums up to 90 degrees. Therefore, the complement of angle x is 90 - x degrees.

The supplement of an angle is the angle that, when added to the given angle, sums up to 180 degrees. Therefore, the supplement of angle x is 180 - x degrees.

According to the given information, the supplement of angle x contains 12 degrees more than twice its complement. Mathematically, this can be written as:

180 - x = 2(90 - x) + 12

Now, let's solve this equation step by step:

180 - x = 180 - 2x + 12
- x = - 2x + 12
x - 2x = 12
- x = 12
x = -12

After solving the equation, we find that the angle x is equal to -12 degrees.

However, angles are typically considered positive and measured between 0 and 360 degrees. Since -12 degrees is not a valid angle in this context, it seems that there might be an error in the given information or problem statement.

Please double-check the problem, as there might be a mistake or missing information that needs clarification.
