tan60° = $\frac{opposite}{adjacent}$ = $\frac{x}{5}$ = $\sqrt{3}$ ( multiply both sides by 5 to clear the fraction )

x = 5 $\sqrt{3}$

Elenna [48]

Answer:

125 students

Step-by-step explanation:

The following table is missing:

3 or more 7

Total 50

From the sample, we can estimate that 25/50 = 0.5 or 50% of the students have exactly two Internet-compatible devices. Then there are 0.5*250 = 125 students who have exactly two Internet-compatible devices in Brianna’s school.
