Answer:

No

The sides of the triangle do not satisfy the Pythagorean Theorem.

Step-by-step explanation:

If we are given the three sides to a triangle, and we are asked to find out if it is a right triangle, we will have to see if the sides of the triangle satisfies the Pythagorean Theorem. The Pythagorean Theorem is:

a² + b² = c²

where c is the hypotenuse and a and b are the other two sides.

So we can see from the image that 28 would be the length of the "hypotenuse" and 19 and 20 would be the lengths of the other two sides. Lets see if these values satisfy the Pythagorean Theorem:

19² + 20² = 28²

361 + 400 = 784

761 ≠ 784

So no, the triangle is not a right triangle because the sides does not satisfy the Pythagorean Theorem.

I hope you find my answer and explanation to be helpful. Happy studying.

Sum of (x+5) and (2x+3)
olga55 [171]

Answer:

3x+8

Step-by-step explanation:

First, we can write the sum into a <em>mathematical expression</em>:

<em>The sum of (x+5) and (2x+3)</em>

<em />

<u>(x+5)+(2x+3)</u>

<u />

<em>However, we do not need the parenthesis. It is unnecesarry here as we are just adding the two parts:</em>

<em />

<u>x+5+2x+3</u>

<u />

Using <em>commutative property</em>, we can rearrange the symbols so that the x's are with each other and the numbers are with each other:

<u>x+2x+5+3</u>

<u />

Now we can <em>simplify</em> the expression:

<u>3x+8</u>

<u />

Hope this helped :)

The pentagon below has an area of 8.3 square centimeters and a side of 2.2. What is the approximate length of the apothem? A.0.4
nalin [4]

Answer:

C. 1.5 cm

Step-by-step explanation:

A pentagon is a polygon with 5 sides.  

The formula for the area of a regular polygon is

A=\frac{1}{2}ap

where a is the apothem and p is the perimeter.  The perimeter is found by multiplying the number of sides of the figure by the length of 1 of those sides:

5(2.2) = 11

Now we have everything we need to solve for the length of the apothem.  

8.3=\frac{1}{2}a(11)

Begin by multiplying both sides by 2 to get rid of the fraction, so

16.6 = 11a  Divide both sides by 11 to get

a = 1.5090909 or

C. 1.5 cm
