[Right Triangle Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use PT to solve for the missing length.

Step 2: Identify Variables

Leg a = 12

Leg b = x

Hypotenuse c = 20

Step 3: Solve for x

Substitute: 12² + x² = 20²
Isolate x term: x² = 20² - 12²
Exponents: x² = 400 - 144
Subtract: x² = 256
Isolate x: x = 16

Tom solved the problem a different way. First he found the total area of the floor, and then he multiplied by the height. Does T

Anastasy [175]

No.

Tom forgot about the area of the top/roof, the floor and roof are different dimensions/areas, making his method incomplete.

He needs to find area of Roof, Floor then times height.

What is 6/10 rounded to the nearest half

belka [17]

6/10 rounding to the nearest half would be 1, not 0.

Reason for this: Here is a number line to help you!

|----|----|

Left line = 0

Middle line = 1/2

Right line = 1

Here is another rule!

0/10, 1/10, 2/10, 3/10, 4/10 = rounded to the nearest half would be 0

5/10, 6/10, 7/10, 8/10, 9/10, 10/10 = rounded to the nearest half would be 1.

So 6/10 rounded to the nearest half is 1.

Hope this helped!

PLEASE HELP 20 POINTS!! QUESTION IS AN IMAGE

prisoha [69]

Okay, so first off, if you need to graph anything, I suggest Desmos, it's a website with an online graphing calculator. It saved my life for highschool geometry.

Now, to answer your question, your y-intercept is going to be at point (0,2). Your x-intercepts are going to be at points (-2,0) and (-4,0). Your point is at (-3,-1). And then your lines simply extend from there.

Hope this isn't too late to be helpful, good luck with your assignments.
