Scalene triangle
Let the third angle be x°
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°
