One of the acute angles of a right angles is 36 degree ,find the other ?

The triangle ABC is a right angled triangle means that angle A=90 

Then angle B+angle C=180 - 90 degrees=90 degrees

Now, angle B= 36 degrees

Therefore, angle C=90-36=54 degrees.

PROOF:-

54+36+90 degrees=180 degrees (angle sum property of a triangle)
