Select all correct answers.

The third angle measures 110°.

The third angle measures 50°.

  1. Answer:
    the sentences that are true are..:
    Two sides have the same length
    The third angle measures 70°
    It is an acute triangle.
    i know that because eat triangle is 180°, so if we subtract 40° and 70° from 180°, we get 70°, meaning the three angles in the triangle are 40°, 70°, and 70°. Because all of the angles are under 90°, we know that it is an acute triangle.
