Answer:

12/13, or answer choice B

Step-by-step explanation:

Ok first lets find the lengths of this triangle. We know 2 lengths already, 5 and 12. By using the pythagorean theorem, a^2+b^2=c^2, we can figure out that the third side is 13 units long.

Math:

5^2+12^2=169

25+144=169

And the square root of 169 is 13, meaning that the hypotenuse of the right triangle is 13.

To remember what SIN TAN and COS mean, you can use this helpful phrase: SOH CAH TOA

SOH: It means that SIN is OPPOSITE OVER HYPOTENUSE

CAH: it means that COS is ADJACENT OVER HYPOTENUSE

TOA: It means that TAN is OPPOSITE OVER ADJACENT

because it asks for SIN B, we need to do OPPOSITE OVER HYPOTENUSE.

Because the side opposite to angle B is 12 units, and the hypotenuse is 13 units, the answer is 12 over 13 units, or 12/13.

I hope my answer helped!

vazorg [7]

Answer:

x - 18°F = 2°F

x = 20°F

Step-by-step explanation:

First, write the equation with the information you know. It dropped 18°F from 6 to midnight, and by midnight the temperature was 2°F

Your equation should look like this: x - 18°F = 2°F

Move the constant to the right hand side and change it's sign:

x = 2°F + 18°F

Add the numbers to get x = 20°F

Hope this helped!

A school made $880 from ticket sales for the school play. From the ticket sales, $250 were from adult tickets.
Alecsey [184]

Answer:

126 Students

Step-by-step explanation:

First, you subtract the money from the adult tickets from the total ($880), that leaves $630.

Since each student ticket is $5, you divide $630 by 5, which equals 126.

So, 126 students attended.
