Two angles are supplementary. If the first angle is 2 times the second angle, what are the measures of both angles?

Step-by-step Solution
Let's denote the first angle as \( A \) and the second angle as \( B \).
Given that the two angles are supplementary, we know that their sum is \( 180^\circ \). So, we have:
\[ A + B = 180^\circ \]
We are also given that the first angle is 2 times the second angle, so we have:
\[ A = 2B \]
Now we can substitute \( 2B \) for \( A \) in the first equation:
\[ 2B + B = 180^\circ \]
Combine like terms:
\[ 3B = 180^\circ \]
Now, divide both sides by 3 to solve for \( B \):
\[ B = \frac{180^\circ}{3} \]
\[ B = 60^\circ \]
Now that we have the measure of the second angle, we can find the measure of the first angle by using the relationship \( A = 2B \):
\[ A = 2 \times 60^\circ \]
\[ A = 120^\circ \]
So, the measures of the two angles are \( 120^\circ \) and \( 60^\circ \).
Quick Answer
The measures of the two angles are \( 120^\circ \) and \( 60^\circ \).
