Questions & Step-by-Step Solutions
If two angles are supplementary and one angle is twice the other, what are the measures of the angles? (2022)
Steps
Concepts
Step 1: Understand that supplementary angles add up to 180 degrees.
Step 2: Let the smaller angle be represented as 'x'.
Step 3: Since one angle is twice the other, the larger angle can be represented as '2x'.
Step 4: Write the equation for supplementary angles: x + 2x = 180 degrees.
Step 5: Combine like terms: 3x = 180 degrees.
Step 6: Solve for x by dividing both sides by 3: x = 60 degrees.
Step 7: Find the larger angle by calculating 2x: 2 * 60 = 120 degrees.
Step 8: The two angles are 60 degrees and 120 degrees.
Step 9: Check if these angles are in the options provided. If not, verify the problem statement.
