Answer:
C 111
Step-by-step explanation:
7 x 6 = 42 x 5 = 210 x 8 = 1,680 x 4 = [ 6,720 ]
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°
It is closer to 1/2 because 5/8 is close to 4/8 which is 1/2.
