Answer:
(x, y) = (10, 4)
Step-by-step explanation:
Opposite sides are the same length, so ...
ON = LM
6x -3 = 4x +17
2x = 20 . . . . . . . . add 3-4x
x = 10
__
OL = NM
x -5 = 3y -7
10 -5 + 7 = 3y . . . . . substitute x, add 7
12/3 = y = 4 . . . . . . simplify, divide by 3
The values of x and y are 10 and 4, respectively.
180°. :)
All angles in a triangle sum to 180° proof.
Answer: I think it’s the 2nd, 3rd and 4th
Step-by-step explanation:
Slope Intercept Form Equation: mx + b = y
Use the slope, like 3/2 or 4, but first plot the y-intercept, like 3, and then put the equation to these: y = 3/2x + 4 or y = 4x + 4. Plot the y-intercept on the y- axis (the vertical line). If you were to use my examples, you would plot the y-intercept by (0,4). Then if you used my first example equation, move 2 to the right of the plotted coordinates and then up by 3. If you were to use my second equation, however, then you would move to the left of the same plotted coordinates, (0,4), 1 to the right and then up 4.
All angles in a triangle add up to 180
180 = 9 + 15 + 2x - 1 + 3x
180 = 24 - 1 + 2x + 3x
180 = 23 + 5x
180 - 23 = 5x
157 = 5x
Divide both sides by 5
X = 31.4 or 157/5
