Answer:

Step-by-step explanation:

we are given that angle NRQ is 78 degrees

we can see from the figure that the sum of the given angles is angle NRQ

(8x + 7) + (4x - 1) = 78

12x + 6 = 78

12x = 72

x = 6

Now, we have to find angle PRQ

replacing x with 6 in the equation of angle PRQ

PRQ = 4(6) - 1

PRQ = 23

Answer:

The distance from earth to sun is 387.5 times greater than distance from earth to moon.

Solution:

Given, the distance from Earth to the sun is about $9.3 \times 10^{7} \mathrm{miles}$

The distance from Earth to the Moon is about $2.4 \times 10^{5} \mathrm{miles}$

We have to find how many times greater is the distance from Earth to the Sun than Earth to the Moon?

For that, we just have to divide the distance between earth and sun with distance between earth to moon.

Let the factor by which distance is greater be d.

$\text { Now, } \mathrm{d}=\frac{\text { distance between sun and earth }}{\text { distance between moon and earth }}=\frac{9.3 \times 10^{7}}{2.4 \times 10^{5}}=\frac{9.3}{2.4} \times 10^{7-5}\\\\=3.875 \times 10^{2}=387.5$

Hence, the distance from earth to sun is 387.5 times greater than distance from earth to moon.
