Question

two acute angles of a right angled triangle are equal. Find the two angles

Answer 1

let the two equal angles be x
therefore 90+x+x=180
2x=180-90
x = 90/2 = 45 degrees
therefore the two angles are 45 degrees

Answer 2

Let the two acute angles be x°
Then,the sum of all the angles of the right triangle is 180°
x+x+90=180
2x+90=180⇒2x=180-90=90
x=90/2=45°
Hence the two acute angles are 45°.
