Answer:
diameter?
Step-by-step explanation:
Hello!
Usually systems of equations have one equation that will show the value of one variable in relation to their other, such as y=2x.
The other equation will usually show the two variables in relationship to another number, such as x+y=15.
To make a system of equations for this point, we need to show one variable’s value in relation to the other. We could put that x=2/3y.
Now we show x and y in relation to another number. We could put that x+y=-5.
Note that we could add y intercepts and extra coefficients to these equations, but for now I am keeping it simple.
Now we have a possible system of equations.
x=2/3y
x+y=-5
When solving for the values of x and y, you could substitute the first equation for x in the second equation to solve.
I hope this helps!
We have that cos30=
by the definition of cos as the ratio of adjacent leg over the hypotenuse. Hence, 7/w=1/2 by eradicating square roots. Solving for w in this equation we get that w=7*2=14.
We have that the 3 sides obey the Pythagoran theorem, because:
Hence, the triangle is right. We also have that one side is half the hypotenuse hence one of the other angles of the triangle is 30 degrees because sin30=1/2. Finally, the third angle is 60 degrees because sum of angles=180.
Here, we have that sin 45=p/44=
. Multiplying by 44, we have that p=22
