This is what I got for you
Answer: B: 41, C: 68, D: 71.
Step-by-step explanation: A triangle's angles have to add up to 180 degrees for it to be considered a triangle. If you were to add up 71, 41, and 68, then it would equal 180 degrees. This means that out of all the other measurements, these are the three possible angle measures that can be used to make a triangle.
(I figured this out by taking 3 random sides from the list there and adding them up to see if they equal 180.)
Answer:
120:80 I think this is the answer
Step-by-step explanation:
![200 \div 5 = 40](https://tex.z-dn.net/?f=200%20%5Cdiv%205%20%3D%2040)
![40 = 1 \: ratio](https://tex.z-dn.net/?f=40%20%3D%201%20%5C%3A%20ratio)
![3 \times 40 = 120](https://tex.z-dn.net/?f=3%20%5Ctimes%2040%20%3D%20120)
![2 \times 40 = 80](https://tex.z-dn.net/?f=2%20%5Ctimes%2040%20%3D%2080)
Answer:
Think of the altitude as a line that divides the equilateral triangle into two equal parts.
Each part is a 30, 60, 90 triangle. The altitude of the triangle corresponds to the x
side of the equilateral triangle.
So: 9=x
, and x=9/
.
However, one side of the triangle is actually 2x, so the correct answer is
18/![\sqrt{3\\}](https://tex.z-dn.net/?f=%5Csqrt%7B3%5C%5C%7D)
