Answer:

x = 2\sqrt{5}

Step-by-step explanation:

Given

The attached triangle

Required

Find x

Using the sin function

sin(\theta) = \frac{Opposite}{Adjacent}

sin(30) = \frac{\sqrt{5}}{x}

Make x the subject

x = \frac{\sqrt{5}}{sin(30)}

x = \frac{\sqrt{5}}{1/2}

Express as:

x = \sqrt{5}/1/2}

x = \sqrt{5}*2/1

x = \sqrt{5}*2

x = 2\sqrt{5}

If cells are: a1=90, a2=85, a3=80, a4=75, and a5=75. what will be your formula if you are going to get the average?
swat32
The average can be given by the following formula:
 Average = (a1 + a2 + a3 + a4 + a5) / (5).
 Equivalently.
 Average = (ai) / (i).
 Where,
 i = 1,2,3,4, ..., n
 Substituting
 Average = (90 + 85 + 80 + 75 + 75) / (5).
 Average = 81
 answer:
 Average = (a1 + a2 + a3 + a4 + a5) / (5).
 or
 Average = (ai) / (i).
 Where,
 i = 1,2,3,4, ..., n
