if a right triangle has an angle that is 55 degrees, what is the measure of the third angle in the triangle?
A right triangle always has one angle measuring 90 degrees, which is one of the defining characteristics of a right triangle. Therefore, the sum of the measures of the three angles in a right triangle always adds up to 180 degrees.
Since one of the angles has already been given as 55 degrees, and the right angle is always 90 degrees, we can find the measure of the third angle by subtracting the sum of the two given angles from 180 degrees:
Third angle = 180 degrees - 55 degrees - 90 degrees
Third angle = 35 degrees
Therefore, the measure of the third angle in the triangle is 35 degrees.
