Question

A triangle has angles measuring 43.5 and 62.8
1. What is the measure of the triangle's third angle?
2. Classify the triangle by sides and angles

1 Answer

  • All 3 angles of a triangle measure 180 degrees.

    43.5 + 62.8 = 106.3

    180 - 106.3 = 73.7

    So the third angle is 73.7.

    This is an acute triangle because all 3 angles of the triangle are less than 90 degrees.

    This is a scalene triangle because all 3 angles are different.
