Need ! a, b, c and d are the four corners of a rectangular plot marked out on level ground. given that the bearing of b from a is 040 degree and the bearing of c from a is 090 degree, calculate the bearing of:
a. b from c
b. a from c
c. d from c

A bearing is an angle measured from North direction clockwise.

In the image attached you can see a sketch of the given problem.

Notice that the bearing of B from C is 40°, because according to the problem, all four points are on level ground, which means they are coplanar, and the angle between the plane and the North is 40°.

The bearing of A from C is also 110°, because it's the bearing of C from A and A from C are same-side internal angles between parallels which must sum 180°.

The bearing of D from C is 40° too, because that setup is parallel to the bearing of B from C.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
