Answer:

$\angle r=16.696$

Explanation:

From the question we are told that:

Dimension

r = 5 cm

t = 6.8 cm

∠T=23°

Generally the equation of sine rule i is mathematically given by

$(sin \angle r)/(R) =(sin \angle t)/(T)$

$( \angle r)/(1) =sin^-^1((sin \angle t*R)/(T))$

$( \angle r)/(1) =sin^-^1((sin23*5)/(6.8))$

$\angle r=16.696$
