Hokiris ladder has two legs that are each 8 feet long. When the ladder is opened safely and locked for use, the legs are 4 feet

guajiro [1.7K]

To solve this problem you must apply the proccedure shown below:

1- The ladder forms an isosceles triangle, because it has two equal sides.

2- Let's call the angle $\alpha$ . To calculate it , you can divide the triangle into two equal right triangles and the angle $\alpha$ will be divided into two equal parts too. Therefore, you can calculate the half of the angle and then multiply it by two, as following:

$Sin^{-1}(\alpha 1)=opposite/hypotenuse$

$Sin^{-1}(\alpha1)=8/2\\ \alpha1=14.47 degrees$

$\alpha =2\alpha 1\\ 2=2(14.47degrees)\\ \alpha =28.95degrees$

The answer is: $28.95degrees$

Aneli [31]

Answer:

They arrived at am and left at pm

Step-by-step explanation:

What do you need to find?

We need to find the time when Lea and her father arrived at the scenic overlook and the time when they left.

What do you need to find first?

First we need to find the exact minutes they arrived and left. Then we have to determine whether it was am or pm

Steps:

1. Noting the time they arrived

They arrived 15 minutes before noon

2. Determining whether it was am or pm

Noon is 12 pm by convention

Midnight is 12 am by convention

3. Calculating the minutes for exact time

Each hour has 60 minutes:

60 - 15 = 45

4. Determining the time(am or pm) after subtracting 15 minutes

which means they arrived at 11:45 am (am is used for time before 12 at noon)

5. They left 12 minutes after the noon:

Noon time is 12 pm

6. Adding 12 minutes to 12pm

The exact time becomes 12:12pm
