Answer:

  30.9 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Cos = Adjacent/Hypotenuse

In this scenario, the side adjacent to the 75° angle is the 8 ft distance from the building. The hypotenuse of the triangle is the ladder. So, we have ...

  cos(75°) = (8 ft)/(ladder length)

  ladder length = (8 ft)/cos(75°) ≈ 30.9 ft

The ladder is about 30.9 feet long.

What is an equation of the line that passes through the point (-1, 4) and is parallel
vesna_86 [32]

Answer:

The answer is

<h2>y + 2x = 2</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is 2x + y = 1

We must first write the equation in the general form above

That's

y = - 2x + 1

Comparing with the general equation above

Slope = - 2

Since the lines are parallel their slope are also the same

Slope of parallel line = - 2

So the equation of the line using point

( - 1 , 4) and slope - 2 is

<h3>y - 4 =  - 2(x + 1) \\ y - 4 =  - 2x - 2 \\ y + 2x =  - 2 + 4</h3>

We have the final answer as

<h3>y + 2x = 2</h3>

Hope this helps you
