Answer:

$\large{x=7.4438\ cm\approx7.4\ cm}$

Step-by-step explanation:

Use tangent:

$tangent=\dfrac{opposite}{adjacent}$

We have:

$\alpha=28^o,\ opposite=x,\ adjacent=14\ cm$

$\tan28^o\approx0.5317$

Substitute:

$\dfrac{x}{14}=0.5317$ multiply both sides by 14

$x=7.4438\ cm$

abruzzese [7]

Answer:

15 students purchase their lunches in the cafeteria.

Step-by-step explanation:

Given:

At eastwood middle school, 25% of the 60 students Mrs. Wade teaches buy their lunches in the cafeteria.

Now, to find the students purchase their lunches in the cafeteria.

Total students = 60.

Percent of students who buy lunches = 25%.

So, to get the number of students who buy their lunches in the cafeteria:

25% of 60.

$=\frac{25}{100} \times 60$

$=0.25\times 60$

$=15.$

Therefore, 15 students purchase their lunches in the cafeteria.
