You have a 20-foot ladder that you are using as you paint your house. you place the ladder so that it forms an angle of 30 at the point of contact between the ladder and the ground. how high will the top of the ladder be above the ground

The Ladder is 10 ft high.

Step-by-step explanation

According to the question we have a 20 ft ladder inclined against a wall at a 30° angle, and are asked to find how high the top of the ladder is from the ground. I have added a visual representation to help you better understand the situation. As you can see we need to solve for x. Since we are given one angle and the hypotenuse we can solve for x using the SIN operator.

Since we have the angle (a) and the hypotenuse we can just plug the information into the sin equation and solve for the opposite (x).

So now we can see that the height of the top of the ladder to the ground is 10 ft

I hope this answered your question. If you have any more questions feel free to ask away at .

c is the correct answer

step-by-step explanation:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
