- 4a
GCSE Maths Quiz
Y = 360 - x because they make a full turn. If x = 2a then y = 360 - 2a. Then z = half of this (angles on a chord again). So z = 180 - a. So, a + z = a +(180 - a) = 180. So opposite angles add up to 180.

Answers
- It's £4.80 as the bill will have come to £5.20.
- It's £1.02. The working: 3.56/7 = 0.509 x 2 = 1.018, which rounded up is 1.02.
- It's $1,365. The working: 750 x 1.82 = 1,365.
- It's 2a. Click NEXT to see our working.
- It's c=2a-b. The working: In an equation with unknowns on both sides, whatever you do to one side you must do to the other. So 3c+b=2c+2a. Now get rid of 2c from both sides. So c+b=2a. Now deduct b from both sides, to get c=2a-b.
- It's 0.00902. The working: move the decimal point three places to the left.
- It's 59.0425 cm sq. The working: with options for answers given to four decimal places, the longest each side can be in mm is 5.6499 x 10.4499, which equals 59.0425 rounded to four decimal places.
