Step-by-step explanation:
Using trig,
We must use cosine to find the missing side.
The equation is cos 60 =
The cosine of 60 is 1/2
So, we multiply 1/2 by 18
to get 9

Answer:
The area of LQM is
Step-by-step explanation:
Given
Area of PNQ = 8
Area of LPQ = 16
See attachment for triangles
The area of PNQ is calculated as:
Substitute 8 for Area
The area of LPQ is calculated as:
Substitute 16 for Area
From the attachment:
Make LP the subject
So:
We have:
and
Equate both expressions:
Divide both sides by PQ
Multiply both sides by 2
Since PNQ is similar to LNM, the following equivalent ratios exist:
Substitute
Area of LQM is:
This gives:
Recall that:
So:
