Problema Solution
In ∆ABC, AC = 15 centimeters, m B = 68°, and m C = 24°. What is BC to two decimal places?
6.58 centimeters
9.88 centimeters
13.57 centimeters
16.17 centimeters
19.25 centimeters
Answer provided by our tutors
m A = 180 - (m B + m C)
m A = 180 - (68 + 24)
m A = 88 degrees
using the Law of sines we have:
BC/sin(88) = AC/sin(68)
BC = 15*(sin(88)/sin(68))
BC = 16.17 cm
