Answer:
160 sq cm
Step-by-step explanation:
Since the two trapezoids are similar, you can use a ratio to find the area.
If we use x to represent the area of ABCD, then the ratio will look something like:
5/20 = 40/x
which then we can solve x to be 160 sq cm.
Answer:
The sine of the angle = the length of the opposite side. the length of the hypotenuse.
The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
The tangent of the angle = the length of the opposite side. the length of the adjacent side.

Answer:
<h3> 8 </h3>
Step-by-step explanation:
16 divided by 8 is 2. 40 divided by 8 is 5. Neither of these can be reduced by any more common numbers, so therefore, 8 is your greatest common factor. The GCF of 16 and 40 is 8.
Use the pythagorean theorem to solve this: a^2 + b^2 = c^2.
You already have a and b which are 3 and 4. Square them up and you will get 9 + 16 = c^2.
Add.
25 = c^2
Lastly, square root both sides.
5 = c
The length of AB is 5.
