Question

41. One of the angle of the triangle is equal to the sum of the other two .If the ratio of
the other two angle is 2:3 then the angles ( in degree) are.​

Answer 1

The other 2 angles are 4x and 5x for some value of x.

If the third angle is y then 4x + 5x + y = 180

And either y = 4x + 5x or 5x = 4x + y.

If y = 4x + 5x, then x = 10 and the angles are 40 and 50 and 90.

If 5x = 4x + y, then x = y and x = 18 and the angles are 18 and 72 and 90.
