You need to find the distance across a river, so you make a triangle. BC is 661 feet, m∠B=103.2° and m∠C=14.4°. Find AB.
kati45 [8]

Answer:

AB = 185.77 feet

Step-by-step explanation:

From the figure attached, in ΔABC,

m∠B = 103.2°, m∠C = 14.4° and side BC = 661 feet

We have to find the measure of side AB.

Since ∠A + ∠B + ∠C = 180°

∠A + 103.2 + 14.4 = 180

∠A + 117.6 = 180

∠A = 180 - 117.6

     = 62.4°

By applying sine rule in the given triangle ABC

\frac{AB}{sinC}=\frac{BC}{sinA}

\frac{AB}{sin14.4}=\frac{661}{sin62.4}

\frac{AB}{0.249}=\frac{661}{0.886}

AB = \frac{0.249\times661}{0.886}

     = 185.77 feet

Therefore, AB = 185.77 feet will be the answer.
