What is the length of GH¯¯¯¯¯¯, to the nearest tenth of a meter? 7.3 m 13.7 m 14.1 m 19.4 m A scalene triangle G H J. The base s

MAVERICK [17]

Using the sine law.
$\frac{GH}{sin\left(45\right)}=\frac{10\:meters}{sin\left(31\right)}$

$GH=\frac{10\:meters}{sin\left(31\right)}\cdot sin\left(45\right)=13.7\:m$

The measure of side GH is 13.7 meters.
