Answer:$133.455
Step-by-step explanation:
The answer
the sum of the angles in a triangle is always 180°
m < B + m < A + m < C = 180°,
let's find m < B,
by applying sinus rule
14/sinB=10/sinC, so sinB= 10xsinB = 14 x sinC and therefore,
sinB=( 14/10 )sinC =7/2 sin 36° =0.82, so arcsinB=55.08°
the answer is C 55.4°
Make more sense ou of this question and I can help you out more ok?
Measure = 1/2 (120-30)
1/2(90)
45
Answer = 45°
