The diagram shows a circle centre O work out the size of angle X work out the size of angle y

x = 116°, y = 20°

Step-by-step explanation:

Since, measure of angle subtended on the center of the circle is twice the measure of angle subtended on the circumference of the circle.

Now, by angle sum property of a quadrilateral.

there is no grid

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
