question 12 and 10

 

[Hamzeh S]

if you extend all 3 lines you get an equilateral triangle
so all three angles out side the figure will be 60( the angle from tangents)
180-60 to get the answer 120

There are only 2 linees EC and CD :/

17) b) u found that AOB is 66 it's the angle in the center , the angle lying on the circumference will be half the angle in the center one of the circle theorems , so b ) 66/2 = 33

19) a) 14*60=480 seconds
b) distance = area under graph
area of trapezium = 0.5*(8+14)*15 = 165 m
c)acceleration = v-u/t = 15-0/(2*60) = 1/8 m/s^2
