Answer:
divide the diameter by 2
Step-by-step explanation:
Answer:
The answer becomes a multiple of the original fraction, which means that if you simplify the result, you will get the original fraction.
Ex:
2/5 * 9/9 = 18/45
18/45 = 2/5
Answer:
25 Percent Increase
Step-by-step explanation:
Mark brainliest ;)
We know that the sum of the interior angles must be 180, so we have
![(3x+1)+(4x-17)+(5x-20)=180 \iff 12x-6=180 \iff 12x=216 \iff x=18](https://tex.z-dn.net/?f=%283x%2B1%29%2B%284x-17%29%2B%285x-20%29%3D180%20%5Ciff%2012x-6%3D180%20%5Ciff%2012x%3D216%20%5Ciff%20x%3D18)
So, the three angles are
![A=3x+1=3\cdot 18+1=55](https://tex.z-dn.net/?f=A%3D3x%2B1%3D3%5Ccdot%2018%2B1%3D55)
![B=4x-17=4\cdot 18-17=55](https://tex.z-dn.net/?f=B%3D4x-17%3D4%5Ccdot%2018-17%3D55)
And we can already conclude that the triangle is isosceles.
