What is the third angle of a right triangle if one of the angles measures 51 degrees
2 answers:
All angles of a triangle add up to 180 degrees. If it's a right triangle, the right angle is 90 degrees. If another angle is 51 degrees then the last angle has to be 180 - 90 = 90 - 51 = 39 degrees.
Since it's a right triangle one angle will be 90° ■■■■■■■■■■■■■■■■■■■■ 90°+51°=141° A triangle is 180° 180°-141°=39° THE THIRD ANGLE WILL BE 39°
