A right angle
It is a right angle triangle and the 3rd angle will measure 30 degrees
The complementary angle is 15 degrees
It is a right angle triangle providing that the 3rd angle is 30 degrees.
It is 15 degrees because complementary angles add up to 90 degrees
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
Complementary angle = 90 - 71 = 19 degrees
Any triangle that has an angle measuring 90 degrees is a right triangle.
