Let the three angles be ∠A,∠B,∠C
and
∠A=2xo
∠B=1xo
∠C=90o
[∵ from the question the given triangle is a right angled triangle. In this one of the angle is equal to 90o)
Now
∠A+∠B+∠C=180o (sum of the angles of a triangle is 180o)
2xo+1xo+90o=180o
3xo=180o−90o
3xo=90o
xo=90/3=30
Now, substitute the value of x in the given angles
∠A=2xo=2×30=60o
∠B=1xo=1×30=30o
Hence the other angles are 60o and 30o
