36/12=3 Which give you the enlargement of the smaller triangle to the bigger one.
You work out the missing side by putting it into an equation:
3(x-10)=39
Then solve it.
First expand the brackets:
3x-30=39
The rearrange to get x on its own and that will be your answer:
3x=39+30
3x=69
x=69/3
x=23

Answer:
350 feet per minute
Step-by-step explanation:
The amount of time it took the plane to descend is 3 hours 14 minutes minus 1 hour 30 minutes.
This means it took 104 minutes for the plane to descend 36,400 feet.
Dividing 36400 by 104, you get 350 which is the average rate of descent in feet per minute.
If you have a graphing calculator, you can simply type it into y= and it will graph it for you. But if you need coordinates, the line runs through (0,2) , (4,5) , and (-4,1)
