Answer:
C
Step-by-step explanation:
Remember the mnemonic: SohCahToa, where:
Let's determine our side lengths first.
Note that our angle is A. So, we have to determine the sides with respect to A.
The opposite side to A is 16.
The adjacent side is 12.
And the hypotenuse is 20.
With this, we can find our trig ratios:
Sine:
Substitute 16 for the opposite and 20 for the hypotenuse. This yields:
Reduce:
Cosine:
Substitute 12 for the adjacent and 20 for the hypotenuse. This yields:
Reduce:
Tangent:
Substitute 16 for the opposite and 12 for the adjacent. This yields:
Reduce:
So, our answers are:
Out of the answer choices, the choice that represents this is C.
So, our correct answer is C.
And we're done!
Answer: The triangles are not similar.
Step-by-step explanation:
Two figures are similar simply if they have the same shape, but not necessarily the same size. In a more mathematical sense, similar figures have the same angle measures and proportionate side lengths.
<em>For reference, side lengths are proportionate when the ratios between corresponding/matching sides are the same.</em>
Since we do not have any angles, we will try using the SSS Similarity Theorem, which states that if all three sides of both triangles are in proportion, then the triangles are similar. We will first list all the side lengths and match corresponding ones.
Since we matched corresponding sides, we can now check whether they have the same ratio).
Not all of the side lengths have the same ratio, so these triangles aren't similar. you must multiply 14 by 9/7 to get to 18, but you need to multiply the other two sides by 4/3 to get to their
