Given 6, 8, and 11 as the three sides of a triangle, classify it as one of the following acute, right or obtuse. Please help and thank you
Answers

Answer:
obtuse
Step-by-step explanation:
You may remember that side lengths of 3, 4, 5 make a right triangle. Doubling those lengths to 6, 8, 10 will still give a right triangle.
The given triangle has a longest side (11) longer than would be appropriate for a right triangle (10), so the largest angle is larger than 90°.
The triangle is obtuse.
__
Comparison of a triangle to a right triangle with two sides the same is one of several ways the triangle can be classified. You can use the Law of Cosines to find the largest angle, or you can use a triangle solver (as we have below).
In case you don't recall that 3-4-5 makes a right triangle, you can use the Pythagorean theorem to find the longest side of a right triangle with the given shorter sides:
hypotenuse = √(6² +8²) = √100 = 10
Your long side is longer, so your largest angle is larger than 90°.
Law of Cosines:
angle = arccos((6² +8² -11²)/(2·6·8)) = arccos(-21/96) ≈ 102.6°

question: solve the solution using substitution.
Answers
Answer:
x = -3
y = -8
Step-by-step explanation:
2y = x - 13
3x = y - 1; let y = 3x + 1
substitute to solve for 'x':
2(3x + 1) = x - 13
6x + 2 = x - 13
5x + 2 = -13
5x = -15
x = -3
solve for 'y':
3(-3) = y - 1
-9 = y - 1
-8 = y
Answer:
(-3,-8)
Step-by-step explanation:
Get one of the variables by themself.
3x = y-1
y = 3x+1
Plug that equation into the other one
2(3x+1) = x-13
Distribute the 2 to 3x+1
6x+2 = x-13
Combine like terms
6x+2 = x-13
-x -x
5x+2 = x-13
-2 -2
5x = -15
Divide by 5 on both sides
5x = -15
÷5 ÷5
x = -3
Find y
3(-3) = y-1
-9 = y-1
+1 +1
y = -8

Becca is painting a birdhouse (rectangular prism) that has a height of 13cm, a width of 5 cm, and a length of 8cm. How much paint will she need if she only uses 1 coat? 26 sq. cm 0418 sq. cm 0 208 sq. cm
Answers
Answer:coo
Step-by-step explanation:Cooke.
The amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².
What is surface area?Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed.
The surface area of rectangular prism can be given as,
[tex]SA=2(wl+hl+hw)[/tex]
Here, (w) is the width, (h) is the height and (l) is the length of the prism.
Becca is painting a birdhouse. The shape of the birdhouse is similar to rectangular prism with dimensions as, height of 13cm, a width of 5 cm, and a length of 8cm.
Now Becca wants to paint this house using 1 coat. As this paint has to be cover each surface of the house. Thus the amount of total paint should be equal to the surface area of the house.
Here, the dimensions of house is as, height of 13cm, a width of 5 cm, and a length of 8cm. Therefore the surface area of it is,
[tex]SA=2(5\times8+13\times8+13\times5)\\SA=418\rm cm^2[/tex]
Hence, the amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².

Step-by-step explanation:
Since they are both equal to y, we can set them equal to each other.

Combine like terms and isolate the x.
x = 5
Plug in the x to either equation to get the value of y.
y = (5) + 2

8 times a certain number is added to 5 times a second number to give 184.the first number minus the second number is -3.find these number .
Answers
Answer:
The numbers are 13 , 16
Step-by-step explanation:
First number be x
Second number be y
x - y = -3 --------------------(I)
x = -3 +y
8x + 5y = 184 ---------------(II)
substitute x = -3 + y in equation(I)
8*(-3 + y) + 5y = 184
-24 + 8y + 5y = 184
-24 + 13y = 184
13y = 184 + 24
13y = 208
y = 208/13
y = 16
Plugin y = 16 in (I)
x - 16 = -3
x = -3 +16
x = 13

Here we have two triangle rectangles, first, we need to remember the Pythagorean theorem.
For a triangle rectangle with cathetus A and B, and a hypotenuse H, we have the relationship:
A^2 + B^2 = H^2
Where H is the side that is opposite to the right angle (the angle of 90°)
In the first image, we can see that the hypotenuse is equal to 8, and one cathetus is equal to 4.
We want to find the value of b, that is the other cathetus.
Then we have:
4^2 + b^2 = 8^2
b^2 = 8^2 - 4^2
b^2 = 48
b = √48
Second image:
in this case, c is the hypotenuse, a and b are the cathetus.
We know that:
a = 5, b = 10
Then we have the equation:
a^2 + b^2 = c^2
Now we can replace the above values:
5^2 + 10^2 = c^2
25 + 100 = c^2
125 = c^2
√125 = c
