Well we know the arc two secant/(secant and tangent lines) intersecting on a point of a circle subtends will be twice of that the angle the two lines make themselves. So in this problem the tang. and sec. lines intersect on the circle so that means the arc they subtend is twice as angle 8. So it is 2 × ∠8 = 220° so ∠8 is 110°

Nikolai has a jar filled with 120 marbles. he has 72 red marbles, 17 blue marbles, 13 green marbles, and 18 purple marbles. what

asambeis [7]

To find the probability of both of these occurring, you will multiply the probability of choosing a blue marble by the probability of choosing a purple marble (with no replacement after the first one).

Probability of choosing a blue marble: 17/120
Probability of choosing a purple marble: 18/119

17/120 x 18/119 = 3/140

You will have a 3/140 chance of both of these occurring.
