the magnitude of a right angle is 90°.
we are asked to find a fraction of 90°.
one sixth as a fraction is 1/6.
therefore to find 1/6th of a right angle we can calculate as follows
1/6 of 90
when we have the 'of' function it means to multiply
\(\frac{1}{6} * 90\)
numerators are multiplied by numerators and denominators multiplied by denominators
\(\frac{90}{6} = 15\)
angle is 15°
therefore 1/6th of right angle is 15°
