Answer:
C
Step-by-step explanation:
From the graph you can see that y changes from -2 to 2, so the range of the function is ![[-2,2].](https://tex.z-dn.net/?f=%5B-2%2C2%5D.)
Since the range of the functions 
and 
is ![[-1,1]](https://tex.z-dn.net/?f=%5B-1%2C1%5D)
and the range of the functions 
and 
is ![[-k,k],](https://tex.z-dn.net/?f=%5B-k%2Ck%5D%2C)
we can state that the correct option is C: 
Check the value at t=0:
Since the right triangle always has a 90 degree angle they are always similar
Answer:
<h2>36°</h2>
Step-by-step explanation:
We know that angles BOC and AOB are complementary angles, that is, the sum 90°. Additionally, we know that
and 
, which can be expressed as
Let's solve for 
Using this vale, we find the measure of angle AOB
Therefore, the answer is 36°.
2 because 4/2=2 hope it works
