1 answer:
DIA [1.3K]2 years ago

Answer:

  65.9 ft

Step-by-step explanation:

The Law of Sines tells us the relationship between an angle and the opposite side. We are given the angle opposite the given side, but we need the angle opposite the side of interest.

__

<h3>third angle</h3>

The sum of angles in a triangle is 180°, so the measure of the angle at the balloon is ...

  angle C = 180° -75° -60° = 45°

<h3>ground distance</h3>

Then the distance between Amaya and Rochelle (c) is ...

  c/sin(C) = r/sin(R)

  c = r×sin(C)/sin(R) = (90 ft)×sin(45°)/sin(75°)

  c ≈ 65.8846

Amaya and Rochelle are about 65.9 feet apart.

X = 7W? + 4w - 6<br> Y =w2 - 11w +13<br> X-Y<br> Your answer should be a polynomial in standard fom.
svp [43]

Answer: w^2-22w+19

Step-by-step explanation:

X=7w+4w-6\\Y=w^2-11w+13\\

(7w+4w-6)-(w^2-11w+13)\\7w+4w-6-w^2+11w-13\\(7w+4w+11w)+(-6-13)-w^2\\22w-19-w^2\\-w^2+22w-19

Normally we wouldn't have our square variable be negative, so in order to get rid of that negative sign without changing the equation is by multiplying by -1

-1(-w^2+22w-19)\\=w^2-22w+19

I need the answer. (will give brainliest)
MatroZZZ [7]

Answer:

6

Step-by-step explanation:

We can use ratios to solve

15 ft            18ft

---------- = -----------

5ft               x

Using cross products

15x = 5*18

15x = 90

Divide by 15

15x/15 = 90/15

x =6

2 + 2= ?<br><br> Just answer this if ur bored
Galina-37 [17]

Answer:

4

Step-by-step explanation:

break the first 2 into its components, 1 and 1 because 1 + 1 = 2.
Break the second 2 into its components, 1 and 1 because 1 + 1 = 2.

Combine all the components. Since they're all ones, you just have to count your fingers 4 times!
1 + 1 = 2. 2 + 1 = 3. 3 + 1 = 4!
1 + 1 + 1 + 1 = 4!

4 is the correct answer.
