Answer:
Step-by-step explanation:
the question is asking for the length of the side labeled x
use Pythagoras' theorem to find that side
where c = x because c represents the hypotenuse in the theorem and x is on the hypotenuse in this problem
c = 
sooo plug in a = 14 and b = 10
c = 
c = 
c = 
c= 17.20465..... ( that's the approx. length of side x in the problem )
since this is a right triangle we could use trigonometry to find the two angles use SOH CAH TOA to remember how those functions fit on the triangle.
Sin(Ф)=Opp/Hyp Cos(Ф)=Adj/Hyp Tan(Ф)=Opp/Adj
since we know the Hyp (hypotenuse) and the side adjacent will be the side with the 10 soooo...
Cos(Ф)=10/17.20465
Ф = arcCos(10/17.20465)
Ф = 54.4623° is the angle on the side with 10
the side with 14 then has an angle of 35.5376°

This is the math section but ok
if yo mean the pyramid shaped thingie then
get a square piece of paper (4 right angles, equal length sides)
fold the paper in half so one corner touches the opposite corner
unfold
repeat but with the other corner that doesn't ahve a crease
unfold
you should have an x in the middle of the paper with 2 valleys facing up
now fold the 4 corners to the middle of the x so you have a smaller square now
flip it over so the flat side is facing you
fold the 4 corners in to the center
fold the square into a valley horizontally
unfold
fold the square into a valley vertically
unfold
flip it over and pry out the 4 corners and manipulate it like in the illustration
This problem can be expressed through the equation:
x+3x+10= 90
To solve it we subtract 10 on both sides
→x+3x=80
Add x and 3x
→4x=80
And divide each side by 4
→x=80/4
→x=20
ANSWER:
20
Answer:
7.2
Step-by-step explanation:
first divide -2 by 5= -2/5
multiply 18 by -2/5=-36/5
divide 36 by 5=7.2
I believe the answer is the second one {starts with (2,-1)}.
To be considered a function, the input which is the x value can only have one output which is the y value. The others have at least one input with multiple outputs.
