Answer:

≈ 53.7° (Option 3)

Step-by-step explanation:

In the figure given above , the lengths of other two sides (excluding hypotenuse) are known to us. So , it would be convenient to use 'tan'.

Length of side opposite to angle 'x' = 15 cm

Length of side adjacent to angle 'x' = 11 cm

Using 'tan' formula - $\tan x = \frac{Side \: opposite \: to \: x}{Side \: adjacent \: to \: x}$ , lets solve this.

$=> \tan x = \frac{15}{11}$

Using inverse tan function , lets find x.

$=> x = {\tan}^{-1}(\frac{15}{11} )$ ≈ 53.74°

Which congruence theorem can be used to prove WXS and YZS?

mariarad [96]

I am going to make what is hopefully not an incorrect assumption and say that since the segmentXSZ is black and the other lines are blue, that XS is congruent to ZS. If that be the case we have a side in each triangle that is congruent to each other and an angle that is marked as congruent. Angles XSW and ZSY are vertical angles. By definition, vertical angles are congruent. In each triangle, then, we have an angle, a side and an angle which gives us the congruency postulate ASA.

Nikki packed unit cubes into a prism, as shown. Which statement about the volume of the box is true?

See the explanation

<h2>Explanation:</h2>

Hello, recall that you need to write complete questions in order to get exact answers. Here we have a missing diagram so I can help you in a general way. A prism is a three dimensional shape that has two identical ends (flat faces

) and the same cross section all along its length. A cube is a special type of prism having six identical square sides. So the volume of a prism given the length of a side as s is:

$V=s^3$

For example, suppose we have a box formed by unit cubes as indicated in the figure below, so the length of one side of the blue box will be:

$s=1+1+1+1+1+1+1+1=8units$

So the volume of the blue box is:

$V=8^3 \\ \\ V=512units^3$
