The measure of one of the angles of a right triangle is 89.
Option (a) is correct.
To choose the measure of one of the angles of a right triangle.
What is right angle triangle?
A right-angled triangle is a type of triangle that has one of its angles equal to 90 degrees. The other two angles sum up to 90 degrees. The sides that include the right angle are perpendicular and the base of the triangle. The third side is called the hypotenuse, which is the longest side of all three sides.
Given that:
The largest angle is always 90º.
The largest side is called the hypotenuse which is always the side opposite to the right angle.
The measurements of the sides follow the Pythagoras rule.
It cannot have any obtuse angle.
One angle in every right triangle is 90, so the other two sum to 180-90=90.
So, other two angles must be less than 90 degrees.
Therefore, the measure of one of the angles of a right triangle is 89.
