Answer:

-sqrt(2)/2

Step-by-step explanation:

5pi/4 lies in the third quadrant with basic angle: 5pi/4 - pi = pi/4

sin(pi/4) = sqrt(2)/2

Since it's in quadrant 3, sin would be negative

sin(5pi/4) = -sqrt(2)/2

sqrt: square root

Solve the formula A=10+ry. solve for y
noname [10]

The given formula A= 10 + ry

Solve for y means we have to make y alone

A= 10 + ry \\

Add -10 on both sides, we get

A - 10 = 10 -10 + ry \\A - 10 = 0 + ryA - 10 = ry

As there is multiplication sign between r and y so to solve for y, divide both side by r

\frac{A - 10}{r} = y\\\\y = \frac{A - 10}{r}

It says ( Find the length of the hypotenuse )<br> ~<br> Pls?<br> Thanks!
Mashcka [7]

Answer:

5

Step-by-step explanation:

In order to solve this problem, we need to use Pythagorem Theorem (a^2+b^2=c^2)

When using the pythagorem theorem the hypoteneuse would be the c^2 and the two other sides would be a and b (the order doesn't matter).

So, our formula would be:

4^2+3^2=c^2

Simplifies into:

25=c^2

In order to remove the exponent 2, we would have to square root both sides by 2. After doing so, you get the answer 5.

Hope this helps! :)
