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 ) ,

$undefined$
