60 degrees and 120 degrees
75 degrees and 105 degrees
Questions & Step-by-Step Solutions
If two angles are supplementary and one angle is three times the other, what are the measures of the angles?
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 three times the other, represent the larger angle as '3x'.
Step 4: Write the equation for the sum of the angles: x + 3x = 180.
Step 5: Combine like terms in the equation: 4x = 180.
Step 6: Solve for x by dividing both sides by 4: x = 180 / 4.
Step 7: Calculate x: x = 45 degrees.
Step 8: Find the larger angle by calculating 3x: 3x = 3 * 45 = 135 degrees.
Step 9: Conclude that the two angles are 45 degrees and 135 degrees.
