Answer:

70 degrees and 150 degrees.

Step-by-step explanation:

Angles in a quadrilateral always sum to 360 degrees. So, 40+100+7x+15x=360. Solving, 140+22x=360, 22x=220, or x=10. Since the other two angles are 7x and 15x, 7(10)=70 degrees and 15(10)=150 degrees.

Sunny_sXe [5.5K]

Answer: $96.15

Step-by-step explanation:

If you study an extra 10 hours per week, for 52 weeks, in total you studied 52 times 10 hours, this is:

52*10 h = 520h hours.

Now, for these 520 hours of hard work, you earn a scholarship valued (in total) at $50,000.

Then how much is worth each one of these 520 hours?

Let's take divide the value of the scholarship evenly into the 520 hours:

$50,000/520h = $96.15.

This means that the hourly return is $96.15
