Left 4 and up 1. x means left and right , y means up and down. x-4 would be left 4, y+1 would be up 1. :)
Answer:
x=9°
∡EFG=25°
Step-by-step explanation:
Answer:25
Step-by-step explanation: 25-14=11, 11*-5=-55
That's a trapezoid,
![A = \frac 1 2 (b+B)h](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%201%202%20%28b%2BB%29h)
![A = \frac 1 2 (4+12) 4 = 32](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%201%202%20%284%2B12%29%204%20%3D%2032)
Answer: 32
But say we didn't know the formula. We can chop out the 4 by 4 square and we have two 45/45/90 triangles side 4 left over, so two 4 by 4 squares,
A = 2(4)(4) = 32
We can think of this as 12 by 4 rectangle with two 4 by 4 right triangles chopped out:
A = 12(4) - 2(1/2)(4)(4) = 48 - 16 = 32
Slope is rise/run
gains 4m height for every 3secons
rise=4m
run=3sec
slope=4/3
if takes 54seconds t
54 times 4/3=72 meters
max height is 72 meteres assuming that it starts from the ground level
