Answer:

The angles in degrees are 20° , 60°, 100°.

Angles in radians \frac{22}{63} ,\frac{66}{63} ,\frac{110}{63}.

Step-by-step explanation:

Sum of angles of a triangle = 180

Smallest angle = x

Largest angle = 5x

Given that the angles are in A.P

Third angle =\frac{x+5x}{2} =\frac{6x}{2} =3x

Hence, x + 3x + 5x = 180

9x = 180

x = 20°

And 3x = 3(20) = 60°

5x = 5(20) = 100°

In Radians

20 = \frac{22}{7} *\frac{20}{180} =\frac{22}{63}

60 = \frac{22}{7}*\frac{60}{180}  =\frac{66}{63}

100 = \frac{22}{7} *\frac{100}{180} =\frac{110}{63}

Therefore, the angles in degrees are 20° , 60°, 100°.

Angles in radians \frac{22}{63} ,\frac{66}{63} ,\frac{110}{63}.
