Question

If a right triangle has an angle that is 55°
, what is the measure of the third angle in the triangle?(1 point)
Responses

180°
180 degrees

35°
35 degrees

55°
55 degrees

90°
90 degrees

Answer 1

The measure of the third angle in a triangle is always 180 degrees minus the sum of the other two angles. In this case, the sum of the other two angles is 90 degrees (55 degrees + 90 degrees = 145 degrees). Therefore, the measure of the third angle is 180 degrees - 145 degrees = 35 degrees.
