Question: In a triangle, if one angle measures 45 degrees and another measures 55 degrees, what is the measure of the third angle? (2019)

Options:

  1. 80 degrees
  2. 90 degrees
  3. 100 degrees
  4. 110 degrees

Correct Answer: 90 degrees

Exam Year: 2019

Solution: 

The sum of angles in a triangle is 180 degrees. Therefore, the third angle = 180 - (45 + 55) = 80 degrees.

Questions & Step-by-Step Solutions

In a triangle, if one angle measures 45 degrees and another measures 55 degrees, what is the measure of the third angle? (2019)
  • Step 1: Understand that the sum of all angles in a triangle is always 180 degrees.
  • Step 2: Identify the measures of the two given angles: one is 45 degrees and the other is 55 degrees.
  • Step 3: Add the two given angles together: 45 + 55 = 100 degrees.
  • Step 4: Subtract the sum of the two angles from 180 degrees to find the third angle: 180 - 100 = 80 degrees.
  • Step 5: Conclude that the measure of the third angle is 80 degrees.
  • Triangle Angle Sum – The sum of the interior angles in any triangle is always 180 degrees.
