  • 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°
