Firlakuza [10]

Answer:

Option C $=8.4672\times10^{13}$

Step-by-step explanation:

Given : Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approximately 5,880,000,000,000 miles.

Suppose a star is 14.4 light years from earth.

To find : How many miles away a star is from earth?

Solution :

In 1 light-year the distance a light can travel is = 5,880,000,000,000 miles.

or = $5.88\times 10^{12}$ miles

In 14.4 lights year the distance is $=14.4\times (5.88\times10^{12})$

$=84.672\times10^{12}$

or $=8.4672\times10^{13}$

Therefore, Option C is correct - $=8.4672\times10^{13}$

What is the measure of angle x?

Kitty [74]

The two horizontal lines are parallel.

This makes the 80 degree angle and the angle ox x and 20 degrees are alternate interior angles and are the same.

This means x + 20 needs to equal 80.

X = 80-20 = 60 degrees.
