15. given the right triangle in the diagram below,
what is the value of x, to the nearest foot?
a. 11
b. 17
c. 18
d. 22

The answer to your question is 18 feet

Step-by-step explanation:

Data

hypotenuse = x

angle = 40°

adjacent side = 14 ft

Process

1.- To solve this problem we use trigonometric functions. The trigonometric function that relates the adjacent side and the hypotenuse is cosine.

            cos Ф  =

Solve for hypotenuse

             hypotenuse =

2.- Substitution

              hypotenuse =

3.- Simplification

               hypotenuse =

4.- Result

               hypotenuse = x = 18.27 ≈ 18 ft

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.
