-10 is your answer
180 degrees makes up every triangle so you subtract 50 and 80 degrees which leaves you with 50 degrees, that angle with the x is equal to 50 then you solve for x by subtracting 60 on both sides of the equal sign and you’re left with x= -10

The unit rate of speed is 52.5 miles per hour

<em><u>Solution:</u></em>

Given that On a trip to visit relatives you drive 1,115.625 miles over the course of 21  hours and 15 minutes

We know that, 1 hour = 60 minutes

21  hours and 15 minutes = 21 hours + (15/60) hours = 21 + 0.25 = 21.25 hours

So they drive 1115.625 miles in 21.25 hours

To find the unit rate of speed of your vehicle in miles per hour, divide the total miles by time taken

unit rate of speed means miles driven in 1 hour

\rightarrow \frac{1115.625}{21.25} = 52.5

So the unit rate of speed is 52.5 miles per hour
