So 12 over 3 is equal to 4 which is a Whole number. meaning Not a fraction, an Integer is a whole number (not a fractional number) that can be positive, negative, or zero. Rational numbers would include this example as well
Hope this helped have a wonderful day/night/afternoon
Answer:
B is the answer
Step-by-step explanation:
Since there is already a 90 degree angle in the right triangle, the other two angles must add up to 90.
![3x + 6 + 2x - 1 = 90](https://tex.z-dn.net/?f=3x%20%2B%206%20%2B%202x%20-%201%20%3D%2090)
![5x + 5 = 90](https://tex.z-dn.net/?f=5x%20%2B%205%20%3D%2090)
![5x = 85](https://tex.z-dn.net/?f=5x%20%20%3D%2085)
![x = 17](https://tex.z-dn.net/?f=x%20%3D%2017)
Plug 17 into both to find the smaller angle
![3(17) + 6 = 57](https://tex.z-dn.net/?f=3%2817%29%20%2B%206%20%3D%2057)
![2(17) - 1 = 33](https://tex.z-dn.net/?f=2%2817%29%20-%201%20%3D%2033)
![33 < 57](https://tex.z-dn.net/?f=33%20%3C%2057)
So 33 is the answer or B
Answer:
y = 90 -5/2 x
Step-by-step explanation:
The angle on the left equals x+3x+x = 5x
The angle on the right equals 2y
The two angles are same side interior angles which are supplementary because the lines are parallel
5x+2y = 180
Solving for y
2y = 180-5x
Divide by 2
2y/2 = 180/2 -5x/2
y = 90 -5/2 x
