Question

A right triangle has an interior angle measuring 31 Which equation could be used to determine t, the measure of the third angle in degrees?

Answer 1

Since the three interior angles of a triangle always add up to 180 degrees, the equation that could be used to determine t would be:

31 + 90 + t = 180

This equation simplifies to:

121 + t = 180

t = 180 - 121

t = 59

Therefore, the measure of the third angle, t, is 59 degrees.
