Answer:
The length of side b is 179 ft
Step-by-step explanation:
Given triangle ABC in which
∠A = 33°, ∠B = 63°, c=200
we have to find the length of b
In ΔABC, by angle sum property of triangle
∠A+∠B+∠C=180°
33°+63°+∠C=180°
∠C=180°-33°-63°=84°
By sine law,
The length of side b is 179 ft
Option C is correct.
First set up the equation:
Then substitute in known values:
and solve for C
Then substitute in known values:
and solve for C
