<h2><u>D.</u></h2><h3>It's incorrect, because 6 squared = 36, 8 squared = 64, add them together and you get 100. 12 squared does NOT equal 100, it equals 144.</h3>

<em>(To find the hypotenuse {longest side of the triangle}, you square the two short sides, add them together, and finally, divide it by the provided number, and see if the number matches the provided number's square.)</em>

Answer:

D) No, because 6²+8²≠12²

Step-by-step explanation:

In order for it to be a right triangle, the sum of the squares of the side lengths must be equal to the square of the hypotenuse.

In this case, 6^2+8^2=36+64=100. Since 100≠144, this means that option D is correct

k0ka [10]

Answer:

56.

Step-by-step explanation:

= -(8-12)+60+(-4)*2

= -(-4)+60+(-4)*2

= 4+60+(-4)*2

= 4+60+-4*2

= 4+60-4*2

= 4+60-8

= 64-8

= 56

Using the slope and the y-intercept, graph the line represented by the following equation. Then select the correct graph. x - y
Marizza181 [45]

The graph that represents the given line with slope and y-intercept is as attached below.

<h3>How to interpret Linear Graphs?</h3>

We are given the equation;

x - y - 3 = 0

Now, the standard way we should put the equation would be in slope intercept form which is; y = mx + c

where;

m is slope

c is y-intercept

Thus, our equation can be rearranged to get;

y = x - 3

Thus, y-intercept is c = -3

The graph that represents the given line is as attached below.

Find the measure of angle x in the figure below: A triangle is shown. At the top vertex of the triangle is a horizontal line ali
tester [92]
Y = 180 - 52 - 59 = 69 degrees . . . . . . . . (angles on a straight line are supplementary, i.e. add up to 180 degrees)

x = 180 - 69 - 63 = 48 degrees . . . . . . . . (sum of interior angles of a triangle is 180 degrees)

Therefore, m/_x = 48 degrees.

Answer:

<h3><u /></h3>

<u>Trigonometric identities</u>

<u />

\large \begin{aligned}\cos^2 \theta + \sin^2 \theta & = 1\\\implies \quad \quad \sin^2 \theta & = 1 - \cos^2 \theta\\\\\tan \theta=\dfrac{\sin \theta}{\cos \theta} \end{aligned}

Therefore, using the <u>identities</u>, the given expression can be <em>simplified</em> as follows:

\large\begin{aligned}\implies \dfrac{1- \cos^2 \theta}{\cos^2 \theta} & = \dfrac{\sin^2 \theta}{\cos^2 \theta}\\\\& = \tan^2 \theta\end{aligned}
