A fire watch tower in a state forest is 250 feet tall. The height, h. of an object dropped from the top of the tower after t seconds is modeled by the function h (t) = —16t^2 + 250. How long would it take an object dropped from the tower to reach a platform 54 feet above the ground?

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
