Answer:

x = 5
y = 20

Step-by-step explanation:

We need x first.

AB = DE

12 = 3x -3

4 = x -1 . . . . . divide by 3

5 = x

Now, we can find y.

∠C = ∠F

7x +y = 55

y = 55 -7x = 55 -7(5)

y = 20

Answer:

70 degrees

Step-by-step explanation:

Moving from one hour number to the next (12 to 1, 3 to 4, etc) moves the hand of the clock 30 degrees. Using this, we know that the hour hand moved 60 degrees to get to the hour number 2. Then, the angle the hour hand moved because of the minute hand can be calculated by doing (20/60)*30=10. So the final answer would be 70 degrees.
