Question

Use Law of Sines and Cosines to find the missing measurements. Round all answers to the nearest tenth.

Answer 1

The figure for the problem statement is given as,

From the above figure,

`\begin{gathered} \theta_1\text{ + }\theta_2\text{ = 130 }_{}\text{ \_\_\_\_\_\_\_\_(1)} \\ 18\cos \theta_1\text{ = 30 cos}\theta_2\text{ \_\_\_\_\_\_(2)} \end{gathered}`

Also,

`d=\text{ 18sin}\theta_1\text{ + 30sin}\theta_2\text{ \_\_\_\_\_\_\_(3)}`

From equation ( 1 ) and ( 2 ) ,
