Set it up as 15x-13+8x+29+2y=180 and then just find a algebra calculator and put that formula in there
This triangle is an isosceles triangle. That means that the two base angles are equal.
You can set the two expressions equal to each other.
15x-13=8x+29
Solving this, you will find that x=6
Now you can plug x into the two expressions.
15(6)-13=77
8(6)+29=77
Those are the measurements of the two angles.
To find the last angle, you know that the angles of any triangle add up to 180 degrees. Using this information, you can add up the 3 angle measurements and set them equal to 180.
77+77+2y=180
y=13
Now plug in y.
2(13)=26
THe three angle measures are 77, 77, and 26

Answer:
length = 10
width = 5
Step-by-step explanation:
So first you divide 8 from 400 which equals 50.
Then so the length and the width has to equal 50 when they are times-ed, and the length is double the width.
So the length is 10
and the width is 5
Final answer:
Given that the volume of a rectangular prism is length x width x height, this problem can be solved by setting up the equation 2w * w * 8 = 400, where w is the width and 2w is the length. Solving this equation, we find that the width is 5 feet and the length is 10 feet.
Explanation:
In mathematics, the volume of a rectangular prism is given by the formula length x width x height. We are given that the volume of the storage container is 400 cubic feet, its height is 8 feet, and the length is twice the width. Let us denote the width as w, then the length is 2w.
From the given volume formula, we have:
Length x Width x Height = Volume
Substituting the values, we get:
2w * w * 8 = 400
Solving this equation, we find:
w^2 = 25
Taking the square root of both sides, we get:
w = 5
Substituting w=5 into 2w, we find the length:
Length = 2*5 = 10
So the width of the container is 5 feet and the length is 10 feet.

Distribute the 1/3 and the -8 through their parentheses
4 + 1/3x = -48 + 8x
subtract 4 from each side
1/3x = -52 + 8x
subtract 8x from each side
1/3x - 8x = -52
combine like terms
1/3x - 24/3x = -52
-23/3x = -52
divide each side by -23/3 (multiply the reciprocal of the divisor)
x = -52 × -3/23
x = 156/23
x = 6 18/23 or 6.78
(1/3)*12 + (1/3)*x = -8*6 - (-8)*x
4 + 1/3x = -48 + 8x
1/3x - 8x = -48 - 4
-23/3x = -52
x = 156/23
