Answer 1

Sum of all angles in a triangle is 180°

c = 180 - 67 - 53 = 60°

Answer: c = 60°

$\dfrac{b}{\sin(b)} = \dfrac{a}{\sin(a)}$

$\dfrac{b}{\sin(53)} = \dfrac{14}{\sin(67)}$

$b = \dfrac{14\sin(53)}{\sin(67)}$

$b = 12.1 \text {(nearest 10)}$

Answer: b = 12.1

$\dfrac{c}{\sin(c)} = \dfrac{a}{\sin(a)}$

$\dfrac{c}{\sin(60)} = \dfrac{14}{\sin(67)}$

$c = \dfrac{14\sin(60)}{\sin(67)}$

$c = 13.2 \text {Nearest tenth}$

Answer: c = 13.2
