Please show workings and diagrams.​

Step-by-step explanation:

First find the measure of angle Q

a) Use law of cosines to find x:

Use the law of sines to find the missing angles:

b) Bearing P from R:

c)  Bearing R from P:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
