Answer:
Then what is the radius of the circle? Since, the tangent of any point of a line is perpendicular to the radius through the point of contact. Hence, radius of the circle = 8 cm.
X = cos 60 x 8
X = 0.5 x 8 = 4
For the first brackets, You can subtract 4 from 8 and that makes 4. For the second bracket, you can add -8 and 4 which gets you 4. You have simplified what is inside the brackets, now you can add them together. 4 and 4 equals 8. So the answer is 8. You can figure it out other ways also

Just subisute values that will work
one easy way is to make one sides equal to only one of the placeholders, like y, and then lug in values in for x exg
x+2y=3
subtract x from both sides
2y=3-x
divideb bith sides by 2
y=-1/2x+3
subsitute valudes for x and get values for y
if x=2 then
y=-1/2(2)+3
y==-1+3
y=2
when x=2, y=2
when y=0 then y=3
