PLEASE HELP Find the value of x.<br> X<br> 15<br> 12
zlopas [31]

Answer: x = 9

Step-by-Step Solution:

Hypotenuse = 15 units

Base = 12 units

Altitude = x units

Using Pythagoras Theorem,

=> Hypotenuse^2 = Base^2 + Altitude^2

(15)^2 = (12)^2 + x^2

225 = 144 + x^2

225 - 144 = x^2

81 = x^2

x^2 = 81

x = √81

=> x = 9

Therefore, Altitude = 9 units

Can someone explain how to do this? I don't get it.
mihalych1998 [28]

Answer: I think 91.9

Step-by-step explanation:

If I remember right, all the angles of a triangle add up to 180 degrees. So taking 22.8 + 65.3 = 88.1, then 180 - 88.1 = 91.9

Sorry if that’s not right! I just wanted to take a crack at it.

What is the range of the function graphed?
victus00 [196]
The correct answer is B) 
-3 < y ≤ 3

You can tell this by looking at the graph. The lowest that it goes is -3. You'll also note that the -3 has an open circle, which means that it isn't includes and thus needs a <.

The highest it goes it 3. You'll note that it has a closed circle, which means it is included and needs a ≤.
