Answer:
-8/8 is the answer do to the formula
Step-by-step explanation:
y2 -y1
x2-x1
So you can get a basic idea of what your actual answer will be in range of.
Example:
10.5+5.5=__
I can safely assume with estimating that it'll be 15.
Now when I actually find the correct answer which is 16, its a safe bet knowing that your estimate is close to your actual answer.
If you make an uneducated guess like saying 10.5+5.5 was 30 then your answer was 16 its makes you wonder how you got an estimate of almost 2x of 16.
Estimates help, so you know what range your real answer would be in.
Hope this helps
Answer:
42 ft squared
Step-by-step explanation:
First you must find the sides and heights of each of the shapes, for instance, the trapezoid, the rectangle, and the triangle. After you find the sides and height you would solve for the area using the three area formulas for each shape. Then once you have the three individual areas you would just add each answer together and get 42.
Formulas:
Trapezoid = 1/2(b1 + b2)h
Rectangle = b x h
Triangle = 1/2bh
The measure of each angel are 36 and 144
<h3>How to determine the measure of each angel?</h3>
Represent the angles with x and y
So, we have
y = x - 108
Supplementary angles add up to 180.
So, we have
x + y = 180
Substitute y = x - 108 in x + y = 180
x + x - 108 = 180
Evaluate
2x = 288
Divide
x =144
Recall that
y = x - 108
So, we have
y = 144 - 108
Evaluate
y = 36
Hence, the measure of each angel are 36 and 144
