Answer:
Step-by-step explanation:
You need to set up a proportion
Let x = NK
7/13 = x/56 Notice that the longest side of the small trapezoid is the denominator of the fraction on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.
Cross multiply
13x = 7*56 Combine the right
13x = 392 Divide by 13
x = 392/13
x = 30.15
NK = 30.15
You do 9-3/6-5 and that is 3/1 so the slope is 3 (y2-y1/x2-x1)
Well fractions are set up over 100 so if it's 100% it would equal 100/100 or your answer, 1.
I would use elimination
2x+3y = 7
2x-y = -5
Subtract those equations
4y = 12
Y = 3
Now plug in 3 for any y value
2x - 3 = -5
2x = -2
X = -1, y = 3
