Witch best explains whether the triangle with the sides lengths of 5 cm, 13cm, and 12 cm is a right triangle

1 answer:

5 0

Using the CONVERSE of the Pythagorean Theorem:
If a^2 + b^2 = c^2, then the triangle is a right triangle. Remember c must be the longest length.
5^2 + 12^2 doe it equal 13^2
25 + 144 ?=? 169
169 ?=? 169 TRUE
These lengths form a right triangle

Aleks04 [339]

Answer:

3( 73/84 )left over

Step-by-step explanation:

She had 6 gallons in total

2/3+1/4+1/2+5/7=179/84 = 2 ( 11/84)

6/1-179/84 = 325/84 = 3(73/84)

She used 179/84

She have left 325/84

179/84 + 325/84 = 6

With mixed numbers:

2 11/84

3 73/84

2+3=5 11/84+73/84= 84/84 =1

5+1=6

What is the area <br> please help me

Angelina_Jolie [31]

The area and perimeter of the picture is 576 inches square and 96 inches respectively

<h3>How to determine the area</h3>

Given that each frame is a rectangle and four frames makes up the picture

Note that the picture takes the shape of a square

Let's find the total perimeter

Perimeter of the picture = sum of the four rectangular frame perimeters

Perimeter = 24 + 24 + 24 + 24

Perimeter = 96 inches

Formula for area of a square = a^2

Where 'a' is the length of the side = 24 inches

Substitute the value of 'a'

Area of the picture = 24^2

Area of the picture = 576 inches square

Thus, the area and perimeter of the picture is 576 inches square and 96 inches respectively.

If one side of a right triangle is 12 feet long and the hypotenuse of the triangle is 7, find the length of the other side of th

Andreas93 [3]

Answer:

9.74 feet

Step-by-step explanation:

the formula for finding a hypotenuse is $a^{2} + b^{2} = c^{2}$ . We can rearrange that to get: $c^2 - b^2 = a^2$ . So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.
