Asked by Akash

The difference between the two acute angles of a right- angled triangle is 2 π/5 radians. Express the angles in degrees.
I’ve multipled 2 π/5 * 180/ π and got the result 72 degree But the answer is 81 degree and 9 degree. Please explain me!!!

They ask for two angles. Their sum is 90 degrees and their difference is 2 pi/5 radians or 72 degrees.

All you did was convert the difference to degrees. You did that right, but that was not the question.

A + B = 90
A - B = 72
2A = 162
A = 81
B = 90 - 81 = 9

Thnx

take one angle as x and other 90-x so , 2pi/5=72deg so, x-(90-x) =72 x=81 and 90-x=9 , so angle1=81deg and angle2=9deg
