Answer:
Step-by-step explanation:
Y is the hypotenuse. It is side opposite to the right angle.
Zis the length opposite theta. It is the side right opposite to the sign.
X is the side adjacent to theta. It is the one that is in contact with that angle apart from the hypotenuse.
Hope this helps
Answer:
Length: 11
Width: 2
Step-by-step explanation:
If length is x then width is x-9
That means:
26 = x+x+x-9+x-9 = 4x-18 which means:
44=4x x=11
Length=x = 11
Width = x-9 = 11-9 = 2
First thing to do is to solve each of these for y. The first one is y=-4x-3; the second one is y=4x-21; the third one is y=4x+21; the fourth one is y=-4x+3. From that you can tell the positive slopes are found in the second and third equations. Those are the ones we will test now for the point (3, -9). y=-9 and x=3, so let's fill in accordingly. The second equation filled in is -9=4(3)-21. Does the left side equal the right when we do the math? -9=12-21 and -9=-9. So the second one works. Just for the sake of completion, let's do the same with the third: -9=4(3)+21. Does -9=12+21? Of course it doesn't. Our equation is the second one above, y+9=4(x-3).
