Answer:

77.12°

Step-by-step explanation:

Given that:

In triangle OPQ

∠P=70°

line q = 83 inches

line p = 80 inches

To find ∠Q; we use the since rule:

\dfrac{Sin \ Q}{q} = \dfrac{Sin \ P}{p}

\dfrac{Sin \ Q}{83} = \dfrac{Sin \ 70}{80}

Sin \ Q= \dfrac{Sin \ 70 \times 83}{80}

\text{Sin \ Q= 0.9749}

Q=Sin ^{-1}( 0.9749)

\mathbf{Q = 77.12^0}
