Hi there!
We can use right-triangle trigonometry to solve.
We are given the HYPOTENUSE and ADJACENT sides, so we must use cosine in this instance.
cosθ = Adjacent/Hypotenuse
We can plug in what is given:
cos(28) = A/17
Solve for 'A':
17cos(28) = <u>15.01 ft</u>
To complete the table we must carefully observe the keypad, we will notice that each number is equivalent to 3 letters of the alphabet except the numbers 7 and 9 which have 4 letters each.
<h3>How does the keypad work?</h3>
Previously, cell phone keypad had a different layout than today. The numbers were related to the letters of the alphabet and the number key was pressed according to the letters that were related.
For example, if you wanted to type the letter B, you would have to press the number 2 key twice.
The relationship of numbers and letters was distributed as follows:
- It had no letters.
- A, B and C.
- D, E and F.
- G, H and I.
- J, K and L.
- M, N and O.
- P, Q, R and S.
- T, U and V.
- W, X, Y, and Z.
According to the above, the table would be completed as follows.
Note: This question is incomplete because there is some missing information. Here is the missing information:
1. Complete this table to show the relation from letter to number.

Answer:
Height = 3.82
Step-by-step explanation:
(3.14)(5)²
(3.14)(25)
= 78.5
300 = 78.5h
300/78.5 = 78.5h/78.5
h = 3.821656051 or approximately 3.82
Answer:
37
Step-by-step explanation
Do what is in the parenthesis first
(5)+4^2x(2)
Exponents next
4^2=16
5+16x2
Multiplication next
16x2=32
You're left with the equation 5+32=37
Answer:
2011
Step-by-step explanation:
Here is the formula.

A = Final Value
P = Starting Value
R = Rate
N = Time in Years
A = 8,000,000,000
P = 5,400,000,000
R = 0.0195
N = Time in Years
Solve for n.
20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.
