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

I need to find the area of the crater
expeople1 [14]
First you need to find the r, if C=2pieR, than 2.4=2pieR now you divide 2.4 by 2 so you got 1.2=pieR now you divide 1.2 by pie and obtained aproximately 0.38 miles, that is your R, now you do pie multiply by 0.38 exposant 2 and there you go, your answer is aproximately 0.45 miles2 :)

.........help...............
stealth61 [152]

Answer:

1. X axis, 8, 3

2. Y axis, 4,-9

Step-by-step explanation:

The rule of reflections that the place opposite of the axis is negative so:

The rule for x-axis reflection is (x,-y)

The rule for y-axis is (-x,y)

For the first one, x has remained the same, so that means it’s a x-axis reflection.

So change -3 to 3

Same for the next one.

-9 is not changed so that means it’s a y-axis reflection.

And the point is 4,-9
