If there is 20 apples to 10 pears. you could say this as a ratio of 20:10 and then simplify this to 2:1.
<span>This means for every 2 apples there is 1 pear.</span>
If two angles are known to be the same, the triangles are similar! If this is true, then by default the third angle will be the same. So, triangles that have two of the same angles MUST be similar!
Answer:

Step-by-step explanation:
For this case we can use the figure attached and we are interested in order to find the value of x.
We have two similar triangles (DEC and ABC) and we can find the scale factor like this:

And now we can apply proportions in order to find the value of x using the two sides DE and BA, since we have the ratio between the triangle DEC and ABC we have this:

And solving for x we got:

And then the distance across the lake would be 2000 ft
The measure of angle APQ should be 90 degrees considering all the angles in a square add up to 360 degrees. NPQ should also be 90 degrees
Answer:
Pythagroean Theorom is the used to find lengths on a triangle.
Step-by-step explanation:
So say you have a triangle that side A is 5 inches long, and side B is 10. you will use the formula a(squared) + b (squared) = C (squared)
Your C side is the Side straight up from the right angle.
One you add these up you will get your C(squared), after you get this you will square root this number to get your answer.
(this isnt the question answer but this will help u get it)
