Answer:
[tex]\angle r=16.696[/tex]
Step-by-step 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
[tex]\frac{sin \angle r}{R} =\frac{sin \angle t}{T}[/tex]
[tex]\frac{ \angle r}{1} =sin^-^1(\frac{sin \angle t*R}{T})[/tex]
[tex]\frac{ \angle r}{1} =sin^-^1(\frac{sin23*5}{6.8})[/tex]
[tex]\angle r=16.696[/tex]
