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

we have

6x+3y=12 -----> line p

Find the slope

3y=-6x+12

y=-2x+4
