The ramp is modelled as shown in the diagram below.
The angle of elevation from the car is the angle form by the horizontal line and the observer eye from the car. In the diagram, this angle is marked by

We use trigonometry ratio to work out the value of





°
Answer:
1/81.
Step-by-step explanation:
3^-4 = 1 /3^4
= 1/81.
If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:
equation a: 2c = d - 8 /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5
<span>The correct result would </span>be: <span>multiply equation a by −3.</span>
To find the total weight of error subtract the measured weight from the actual weight
3900kg (actual weight) - 3867kg (measured weight) = 33 kg erorr
