Scalene triangle

Let the third angle be

Then,

First angle = (x + 2)°

Second angle = (2x - 5)°

Now,

We know that sum of angles of triangle is 180°.

So,

x + (x +2) + (2x - 5) = 180

4x - 3 = 180

4x = 180+3 = 183

x = 183/4 = 45.75°

Then,

First angle => x +2 = 45.75+2 =47.75°

Second Angle => 2x - 5 = 2×45.75-5 = 91.50-5 = 86.5°

Third angle = x = 45.75°
