Answer:

$x\approx24^\circ$

Step-by-step explanation:

We know that r and s have a combined length of 70. Therefore:

$r+s=70$

Notice that we can determine r by using the Pythagorean Theorem. In this case, r is the hypotenuse, and 20 and 8 are the legs. Therefore:

$a^2+b^2=c^2$

Substituting 20 and 8 for a and b and r for c yields:

$20^2+8^2=r^2$

Compute:

$464=r^2$

Therefore:

$r=\sqrt{464}=\sqrt{16\cdot 29}=4\sqrt{29}$

Now, we can determine s. We know that:

$s+r=70$

So, by substitution:

$s+4\sqrt{29}=70$

Therefore:

$s=70-4\sqrt{29}$

Now, notice that, with respect to x, 20 is the opposite side and s is the hypotenuse.

Therefore, we can use the sine ratio. The sine ratio is the ratio between a right triangles opposite side to its hypotenuse.

In this case, the opposite to x is 20, and the hypotenuse is s, or 70-4√29. Therefore:

$\displaystyle \sin(x^\circ)=\frac{20}{s}$

By substitution:

$\displaystyle \sin(x^\circ)=\frac{20}{70-4\sqrt{29}}$

Take the inverse sine of both sides:

$\displaystyle x^\circ=\sin^{-1}\Big(\frac{20}{70-4 \sqrt{29}} \Big)$

Use a calculator. Therefore:

$x\approx24.37^\circ\approx24^\circ$

<h2>○=> <u>Correct option</u> :</h2>

$\color{plum}\bold{(C)}$ Diameter of circle P is the same length as the radius of circle Q.

<h3>○=> <u>Steps to derive correct option</u> :</h3>

Given :

Diameter of circle P = 26 cm

Radius of circle P :

$=\tt \frac{diameter}{2}$

$= \tt \frac{26}{2}$

$\color{plum} = \tt13 \: cm$

Thus, radius of circle P = 13 cm

Diameter of circle Q = 52 cm

Radius of circle Q :

$= \tt \frac{diameter}{2}$

$=\tt \frac{52}{2}$

$\color{plum}= \tt26 \: cm$

Thus, radius of circle Q = 26 cm

Radius of circle R = 52 cm

Diameter of circle R :

$=\tt radius \times 2$

$=\tt 52 \times 2$

$\color{plum} = \tt104 \: cm$

Thus, the diameter of circle R = 104 cm

☆ Conclusion :

▪︎Diameter of circle P is the same length as the radius of circle Q.

Therefore, the correct option is <em>(C) Diameter of circle P is the same length as the radius of circle Q.</em>
