Daniel claims that any two right triangles can be proven to be similar by the sas similarity theorem because both have right ang
2 answers:
SAS similarity theorem: When two triangles have
corresponding angles that are congruent and corresponding sides
with identical ratios, the triangles are similar.
Two right angles are always congruent, but corresponding sides not always have identical ratios. For example, first right triangle has two legs of 3 and 4 lengths. Second triangle has two legs of 5 and 12 lengths. Then
. That is the mistake.

Answer:
20 feet long
Step-by-step explanation:
To solve this you need to use the Pythagorean theorum, , where c is the length of rope needed and A and B are the side lengths. Think of it like a right triangle.
So, the equation is
Which is then
And the possible values of c are 20 and -20.
From here we know the answer cannot be -20 because you cannot have a negatively long length of rope, so the answer must be 20 feet.
Answer:
Closed and Bounded.
Step-by-step explanation:
Hi there!
1) Let's start by finding the values in which the function is defined. Remember that this can be rewritten:
Since every quadratic root are defined for values 0 then, this help us to understand that we need calculate what interval this Domain is:
2) Graphically speaking, the domain is closed. For the values -2 and 2 are included, and bounded.
Bounded functions have all of their points contained by some circle origin centered. Check it out below.
