2) step one: square the two numbers that aren’t the hypotenuse(the longest side-opposite the right angle).
Step two: add the two numbers together
Step three: square the hypotenuse
If the two values squared and added together equal the hypotenuse squared then it is a right angled triangle.
3) a triangle with the side lengths of 11cm, 13cm and 15cm wouldn’t be a right angled triangle.
Because 11^2 + 13^2 = 290 and 15^2 = 225, therefore it isn’t a right angled triangle because 290 doesn’t equal 225.

what is the value of x?
Answers
Answer:
x = 6
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{FG}{MN}[/tex] = [tex]\frac{GH}{NP}[/tex] , substitute values
[tex]\frac{12}{x}[/tex] = [tex]\frac{20}{10}[/tex] = 2 ( multiply both sides by x )
12 = 2x ( divide both sides by 2 )
6 = x
A woman has 31 coins in her pocket, all of which are dimes and quarters. If the total value of the coins is $ 5.65, how many dimes and how many quarters does she have?
Answers
Answer:
14 dimes and 17 quarters
Step-by-step explanation:
d and q are the number of dimes and quarters, respectively.
"31 coins, all of which are dimes and quarters."
d+q = 31
d = 31-q
"the value of the coins is $5.65"
0.10d + 0.25q = 5.65
substitution
0.10(31-q) + 0.25q = 5.65
3.10-0.10q + 0.25q = 5.65
0.15q = 2.55
q = 17
d = 31-q = 14

Answers
Answer: Height = 41 in
Step-by-step explanation:
Alrighty, I was trying to dodge this question but I guess I'll have to split my brain cells.
To find the Height we can turn the information we have into an equation
15,577.54 = 3.14 * 11 ^ 2 * h
we do some distrubutive property
15,577.54 = 3.14 * 121 * h
15,577.54 = 379.94 * h
15,577.54 = 379.94h
divide by 379.94
H = 41
THE HEIGHT IS 41 YAY ( My head hurts )

The cone shown has a radius of 6 inches and a slant height of 10 inches. What is the total surface area of the cone?
Answers
Answer:
[tex]A=301.71\ \text{inches}^2[/tex]
Step-by-step explanation:
Given that,
The radius of a cone, r = 6 inches
The slant height of the cone, l = 10 inches
We need to find the total surface area of the cone. It is given by :
[tex]A=\pi rl+\pi r^2[/tex]
Substituting all the values,
[tex]A=\pi r(l+ r)\\\\A=\dfrac{22}{7}\times 6\times (10+ 6)\\\\A=301.71\ \text{inches}^2[/tex]
So, the total surface area of the cone is [tex]301.71\ \text{inches}^2[/tex].

Step-by-step explanation:
If yo have the pairs (a, b) and (c, d)
The distance between these two points is:
distance = √( (a - c)^2 + (b - d)^2)
Here we want to find the distance between points B and C.
We can see that the coordinates of each one are:
point B: (-5, 5)
Point C: (-1, 2)
Then the distance between these points is:
AB = √( (-5 -(-1))^2 + (5 -2)^2) = 5
AB = √( 4^2 + 3^2)
Then the correct option is A

Answers
Answer:
(x-2) 2
Step-by-step explanation:
Answer:
We see that the equation: x^2 - 4x + 4 is a perfect square trinomial as it is in the form of a^2 + 2ab + b^2, meaning that it is the square of a binomial. In this case, we see that we can multiply (x-2) with itself to obtain x^2 - 4x +4.
So the factored form is : (x-2)^2, or (x-2)(x-2)
We can check this by multiplying this out, and we obtain the same trinomial.
x^2-2x-2x+4
x^2-4x+4
