1 answer:

7 0

You would use the formula nCr

n= 5 which is the number of letters available which are D E F G H

r= 4 sample of letters

you can easily plug into the calculator... or work with the formula!

5C4 = 5

so there are 5 combinations

Answer:

x ≈ 25.4 Km

Step-by-step explanation:

Using the tangent ratio in the right triangle on the right

tan54° = $\frac{opposite}{adjacent}$ = $\frac{opp}{17}$ ( multiply both sides by 17 )

17 × tan54° = opp , thus

opp ≈ 23.4

-------------------------------------------

Using the cosine ratio in the right triangle on the left

cos23° = $\frac{adjacent}{hypotenuse}$ = $\frac{23.4}{x}$ ( multiply both sides by x )

x × cos23° = 23.4 ( divide both sides by cos23° )

x = $\frac{23.4}{cos23}$ ≈ 25. 4 Km ( to the nearest tenth )
