1. The diagram below. which is not drawn to scale, represents the positions of
three mobile phone masts.
Mast Q is on a bearing of 100% from mast P and is 40km away.
The bearing of mast R from mast Q is 150.
Masts P and R are 66km apart.
Use the information in the diagram to establish the size of angle PQR
(b)
Hence find the bearing of mast P from mast R.

i think this could be a possible answer (1 / 84) -1

good luck! : d

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
