Answer:
You have a chance of getting any of those.
Step-by-step explanation:
If you were to flip the first coin, and it would be either heads or tails 50% chance.
If you flipped the second coin, without cancelling the first, it would be 25% chance
If you flipped the third coin, without cancelling the first it would be 12.5% chance
(this is all for heads)
(20 + 12) - 8, since the question states n is EIGHT less than the sum of 20 and 12.
In a trapezoid, two opposite sides are parallel and are called bases.
In this trapezoid, the top and bottom sides are parallel and are the bases.
The right side that intersects both bases is a transversal.
When parallel lines are cut by a transversal, same-side interior angles are supplementary. The measures of supplementary angles add to 180 deg.
x + 72 = 180
x = 180 - 72
x = 108 deg
