Question

2 angles of a right angled triangle are equal. find the measure of all its angles.
​

Answer 1

Answer:

The angle sum if a triangle is 180. Let the 2 unknown equal angles be x. x + x = 2x. thus, each of the equal angles measure 45 degrees

Answer 2

Let the value of one acute angle = x

Sum of whole angle of triangle = 180°

x + x + 90° = 180°

2x + 90° = 180°

2x = 180° - 90°

2x = 90°

x = 90° ÷ 2

x = 45°

Value of two acute angles = 45°
