See my previous answer to this same question. the vertical angles have to be right angles

To solve this, we need to know what vertical angles and what supplementary angles are. Vertical angles are each of the pairs of opposite angles made by two intersecting lines. And, by the Vertical Angles Theorem, we know that they have the same measure. Now onto supplementary angles. Supplementary angles are angles that add up to 180 degrees.

Let's say that one of the vertical angles is equal to x. That means that the other one is also equal to x, and their sum is 2x. Since we are trying to find out a situation where vertical angles are supplementary, or equal to 180 degrees, that means that 2x is equal to 180 degrees. This is satisfied only when x = 90 degrees, meaning that vertical angles are supplementary when they are right angles.

Answer:

so if we make a pie chart

there's 25 marbles

it'll be 1/25 or 4% chance

a red marble is 5/ 25 or a 20% chance

say if you replace the white on the chances of you getting red will be 24% or 6/25 chance of getting red
