Step-by-step explanation:

Given

Angles: 53, 55 and 72

Required

Match with the correct angle

The question is incomplete as the options that gives hints on what's to be done are not given.

So, I will convert each angle in degrees to radians.

By conversion:

$1^\circ = \frac{\pi}{180}\ rad$

So, we have:

$1.\ 53^\circ$

$1^\circ = \frac{\pi}{180}\ rad$

Multiply both sides by 53

$53 * 1^\circ = 53 * \frac{\pi}{180}\ rad$

$53 ^\circ = \frac{53\pi}{180}\ rad$

The fraction cannot be further simplified

$2.\ 55^\circ$

$1^\circ = \frac{\pi}{180}\ rad$

Multiply both sides by 55

$55 * 1^\circ = 55 * \frac{\pi}{180}\ rad$

$55 * 1^\circ = \frac{55\pi}{180}\ rad$

Simplify fraction

$55^\circ = \frac{11\pi}{36}\ rad$

$3.\ 72^\circ$

$1^\circ = \frac{\pi}{180}\ rad$

Multiply both sides by 72

$72 * 1^\circ = 72 * \frac{\pi}{180}\ rad$

$55^\circ = \frac{72\pi}{180}\ rad$

Simplify fraction

$55^\circ = \frac{2\pi}{5}\ rad$
