B. about 9.1
C. about 18.1
D. about 28.3
Please help me

Answer 1

Answer:(b)

Explanation:

Given

GK=16 units

KH=y units

using Sine rule

$\frac{\sin G}{y}=\frac{\sin H}{16}\\\frac{\sin 30^{\circ}}{y}=\frac{\sin 62^{\circ}}{16}\\y=16\times \frac{\sin 30^{\circ}}{\sin 62^{\circ}}\\\\y=16\times \frac{0.5}{0.883}\\y=9.06\ \approx \ 9.1\ units$
