this shape is a 30-60-90 triangle, which means that the angles of the triangle are each 30°, 60° and 90°. given that the measures of the angles of the triangle are known, as well as one side, we can find the measures of all the other sides (example attached). a 30-60-90 triangle is special because of the relationship of its sides. the hypotenuse (directly across from the 90° angle) is equal to twice the length (2x) of the shorter leg, in this case labeled 'x' and directly across from the 30° angle. the longer leg, across from the 60° angle, is equal to multiplying the shorter leg (x) by √3 or x√3.
since the measure of the hypotenuse is given at 18, we can set the expression of that side equal to 18 and solve for x:
2x = 18 or x = 9
an event with a probability of 0 is impossible.
an event with a probability of 1 is certain.
probability is typically expressed in terms of a fraction between 0 and 1 where the denominator is the total number of outcomes and the numerator is the number of desired outcomes. since probability is expressed as a fraction, if the probability is 0, that means it is impossible, or there is no chance that the event can happen. however, if the probability is 1, that means that the event is certain to happen and the odds are completely in your favor that the event will happen.
