Ms. McGuirk wants to know if she built her son's new sandbox with a perfect right angle or not? The shorter sides are 15 feet an
spayn [35]

Answer:

17 feet

Step-by-step explanation:

A right angle has 3 sides: the adjacent, the opposite and the hypotenuse.

The hypotenuse is the largest side of the right angle

The shorter sides are 15 feet and 8 feet which should represent opposite and adjacent sides respectively

Opposite = 15 feet

Adjacent = 8 feet

Hypotenuse = x feet

Using Pythagoras theorem to solve

Hypotenuse ² = opposite ² + adjacent ²

x² = 15² + 8²

x² = 225 + 64

x² = 289

Find the square root of both sides

√x² = √289

x = 17 feet

The 3rd side is 17 feet

What is the value of |−44|?
julsineya [31]
Hey there!

Here is your answer:

The proper answer to this question is "44" .

Reason:

Think of it like this:

| | <---- This represents a car wash

When you add a positive or negative number in between the lines it represents a car going through the car wash.

So if...

|-44| (goes through the car wash)=44
|44| (goes through the care wash)=44

Therefore it would equal 44.

If you need anymore help feel free to ask me!

Hope this helps!
