ANSWER

EXPLANATION
The given triangle is a right triangle.
It was given that,

and

Using the Pythagoras Theorem, we can determine the value of c.




The ratio is the adjacent over the hypotenuse.

We rationalize to get:

Answer:
2
Step-by-step explanation:
Answer:
The rule is +2
This is the 194th term
Step-by-step explanation:
This is an arithmetic sequence because 2 is added every time.
2x + 1 = 389
2x = 388
x = 194
194* 2 + 1 = 389
mark brainliest please!
5 times as many. Since dog B has 2 and dog A has 10, A = 2 * X, since you’re solving for the multiplication comparison. 10/2 = 5, so you’ve got 5 times as many.
First way
arcsin(1/4) means that 1/4 sin of the angle.
sin(α)=1/4
sin²α+cos²α=1
(1/4)²+cos²α=1
cos²α=1-1/16 =15/16
cosα=+/-(√15)/4
<span>Second way
</span>
sin(α)=1/4 =opposite leg/hipotenuse
cos(α)=adjacent leg/hypothenuse
adjacent leg =√(hypotenuse²- Opposite²)=√(16-1)=√15
cosα=+/-√15/4
For one value of sinα, possible 2 values of cosα.
