Answer:
a) centre angles are double the circumference
b) 60 degrees
c) 120 degrees
Step-by-step explanation:
for c) the opposite angles in a cyclic quadraleteral add to 180 so take 60 from 180 to get 120
Answer:
x = 6
Step-by-step explanation:
to evaluate this 1/2 (4x + 16) = 20 we need to open the bracket and then cross multiply and finally evaluate for the value of x
1/2 (4x + 16) = 20
4x + 16 = 2 x 20 ............................... using cross multiplication
4x + 16 = 40
combine the like terms together
4x = 40 -16
4x = 24
divide both sides by the coefficient of x
4x/4 = 24/4
x = 6
therefore the value of x in the expression 1/2 (4x + 16) = 20 is evaluated to be equals to 6

To figure the problem out you would do:
0.05×64
=3.2
Then you would subtract:
64-3.2=60.8
60.8 is your answer
