Math question no Guessing and Please show work

Answer 1

(B)
Angle c = 86 [angle sum property]

Angle A = 57
The side a opposite of angle A is 'a'. side a is 11
side a ÷ angle A = 0.19298245614
angle c = 86
Angle C × 0.19298245614 = side c
86 × 0.19298245614 = 15.7

Answer 2

Hope u like my process
=====================

According to problem,

$= > \bf \sin( \theta ) = \frac{p}{h} \\ \\ = > \sin(57) = \frac{a}{c} \\ \\ = > \bf c = 11 \times \sin(57) \\ \\ = > \bf \: c = 0.8368 \times 11 = 13.11$


So the required value of c is 13.1
