Find x round your answer to the nearest integer.

daser333 [38]

Answer:

Step-by-step explanation:

Note that x is opposite to the given angle and we are also given the hypotenuse.

Since we have an angle and the side opposite to it and the hypotenuse, we can use the sine ratio. Recall that:

$\displaystyle \sin \theta =\frac{\text{opposite}}{\text{hypotenuse}}$

The opposite side is x, the hypotenuse is 15, and the angle is 53. Substitute:

$\displaystyle \sin 53^\circ = \frac{x}{15}$

Solve for x:

$x=15\sin 53^\circ$

Use a calculator (make sure you're in Degrees Mode!). Hence:

$x=11.9795...\approx 12$

Our answer is C.

Determine if the card below represents a reflection over the x-axis or a

gtnhenbr [62]

Answer:

Reflection over y-axis

Step-by-step explanation:

We know that with a reflection of the x-axis, we flip the value of the y value

But since the y-values in Q3 and Q4 are both negative, we know that can't be the case

So it has to be a reflection over the y-axis where the x-values are flipped

Hope this helps

What is the approximate area of the shaded portion of the diagram? (Use 3.14 as an estimate for pi.)

Nadusha1986 [10]

Answer:

218

Step-by-step explanation:

first find the area of the circle-

$A=\pi r^{2} \\A=\pi 10^{2} \\A=100\pi \\A=314$

to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).

$a^{2} +b^{2} =c^{2} \\a^{2} +16^{2} =20^{2} \\a^{2} +256=400\\a^{2} =144\\a=12$

Now I know the height is 12. Find the area of the triangle

$A=\frac{1}{2} bh\\A=\frac{1}{2} (16)(20)\\A=96$

subtract the area of the triangle from the area of the circle

314-96=218
