The technique I use is add up the numbers in the ratio. You get 2 + 4 + 4 = 10. Now to find the angles, you have to find the fraction of each number in the triangle. So
![\frac{2}{10}\times 180 = 36](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B10%7D%5Ctimes%20180%20%3D%2036)
. Since the other two angles are 4 and 4, which are two times of 2, we can say the other two angles are 72 degrees each.
Y = x + 1......slope = 1, y int = 1
y = x + 2.....slope = 1, y int = 2
In y = mx + b form, the slope can be found in the m position and the y int can be found in the b position.
if the equations have the same slope, but different y int, then u have a set of parallel lines which never cross...therefore they have no solution and are inconsistent

Step-by-step explanation:
1.
is the area under the curve to the left of
, which is a trapezoid with "bases" of length 2 and 5 and "height" 0.2, so
![P(X](https://tex.z-dn.net/?f=P%28X%3C5%29%3D%5Cdfrac%7B5%2B2%7D2%5Ccdot0.2%3D0.7)
2. Find the area under the curve for each of the specified intervals:
(triangle with base 2 and height 0.2)
(triangle with base 1 and height 0.4)
(trapezoid with "bases" 0.2 and 0.4 and "height" 2)
(trapezoid with "bases" 0.1 and 0.3 and "height" 2)
Multiply 10 times 5 then divide it by 4
