Question

Answer:

A straight line (or two rays in a straight line) = 180o
to find x start with this equation
31 + x + 40 = 180 Now get all the numbers on the right.
(31 + 40) + x = 180
x = 180 - (31 + 40)
Only A or C can be correct. It is C, but you have to be very careful how you eliminate A
C <<<< answer.

x = 180 - 31 - 40 is the correct way to remove the brackets.
x = 180 - 71
x = 109

There are better ways to do this particular question without using brackets.
