Answer:

x = 12

Step-by-step explanation:

In a right triangle (a triangle that has a ninety degree angle in it) the the square of the side opposite the right angle is always equal to the sum of the squares of the other two sides. Therefore, we can use the information we are given to figure out the missing side:

15^2=225\\9^2=81\\225-81=144\\\sqrt[2]{144}=12

Good evening

Answer:

D. x = 12

Step-by-step explanation:

Since this a right triangle we can apply the Pythagorean theorem

The graph of a function f is shown below.<br> Find f (2)
liberstina [14]

Answer:  f(2) is 3.

Step-by-step explanation:

f(2) just means "what is the vale of the function, f, when x = 2?  Look for x=2 and read the y value where the line crosses x=2, in this case, the y value is 3.  So f(2) = 3.

======

[One could also determine the equation for the line.  Provided below.]  

The slope is -(1/2) and the y-intercept is 4:

y = -(1/2)x + 4

For x=2,

y = -(1/2)*(2) + 4

y = 3  

y(2) = 3

Two parallel lines are crossed by a transversal. Parallel lines u and w are cut by transversal t. At the intersection of lines u
lilavasa [31]

Answer:

I think it's 105.

Step-by-step explanation:

The wording is sort of unclear, but I drew it out and it seems that they are alternate interior angles. Alternate interior angles are congruent! If this is not the right answer, please tell me and I might be able to tell another one.

Well, technically, it has to be either 75 or 105, because all of the special relationships of triangles are either that they are supplementary or they are congruent. So if it's not 105, try 75 :)
