Find the image of (–7, –3) reflected across the x-axis. A. (–7, 3) B. (7, –3) C. (7, 3) D. (–7, –3)

Naddika [18.5K]

Answer:

(-7, -3) (Answer A)

Step-by-step explanation:

We start with the point (-7, -3). The x-coordinate does not change at all if we reflect this point across the x-axis. Whereas the y-value of (-7, -3) is -3, we end up with +3 after this reflection. The desired image is (-7, +3) (Answer A)

In ΔRST, m < R = 104°, r = 20, and t = 10. Find the m < S, to nearest degree.

Mrrafil [7]

Answer:

47°

Step-by-step explanation:

The law of sines helps you find angle T. From there, you can find angle S.

sin(T)/t = sin(R)/r

sin(T) = (t/r)sin(R) = (10/20)sin(104°)

T = arcsin(sin(104°)/2) ≈ 29°

Then angle S is ...

S = 180° -R -T = 180° -104° -29°

∠S = 47°

The equation cos−1 = x can be used to determine the measure of angle BAC.

Sergio [31]

we know that

in the right triangle ABC

the value of cosine of angle x is equal to

$cos(x)=\frac{AC}{AB}$

we have

$AC=3.4\ cm\\AB=10\ cm$

substitute the values

$cos(x)=\frac{3.4}{10}=0.34$

Find the measure of angle x

$x=cos(x)^{-1} =arc\ cos(0.34)=70.12\°$

Round to the nearest whole degree

$x=70\°$

therefore

<u>the answer is</u>

$70\°$
