Answer:
x = 14
y = 14
z= 14
Step-by-step explanation:
Notice that the top triangle is a 45-45-90 triangle and the triangle below is a 30-60-90 triangle.
Using the fact that the top triangle is a 45-45-90 triangle and also an isosceles triangle, we can see that <em>x</em> will be the same as its respective leg, 14
Now, we must find a side length of the bottom triangle. We can use the Pythagorean Theorem to find the third side of the top triangle, which is also a side of the bottom triangle. We can find that the third side must be 28. We can now use this to find the other sides of the bottom triangle.
Since <em>y</em> is opposite to the 30 degree angle, it is half of the hypotenuse. The hypotenuse which we found earlier is 28, therefore, <em>y</em> is 14. <em>z </em>is then 14
using either Pythagorean Theorem or special right triangle properties for 30-60-90.
Answer:
3
Step-by-step explanation:
its 3 because the line goes through 3 on x axis of the graph
Answer:

Step-by-step explanation:
We can substitute the given values of
,
, and
to find the value of this expression.


We know that <em>two negatives make a positive. </em>This means that
will be the same this as 

Adding a negative is the same as subtracting a positive.

Answer:
Perimeter= 12y units
3y(4) = 12y
Step-by-step explanation:
3y + 3y + 3y + 3y= 12y
For this case we must simplify the following expression:

We have that by definition of properties of powers that is fulfilled:

Then, rewriting the expression:
