Answer 1

The necessary part of the law of sines is:
\[\frac{a}{\sin A}=\frac{b}{\sin B}\]
When the triangle is drawn, line BC is a = 18, line AC is b = 22, angle theta is A and angle B = 135 degrees
\[\frac{18}{\sin \theta}=\frac{22}{\sin 135}\]
\[\sin \theta=\frac{18}{22}\times \sin 135\]
Can you calculate this?
