The hour hand of a clock stopped, but the minute hand continued to move for 155 minutes. How many degrees would the hour hand have moved if it had not gotten stuck??
2. Is the converse of a theorem also true?
3. How much longer is the arithmetic mean than the geometric mean of 18 and 50??
4. Consecutive angles of a quadrilateral are in a ration 3:4:5:6
this implies that the quadrilateral
a. can be inscribed in a cirlce b is a kite
c is a trapezoid d has congruent diagonals
e is not convex
5. The supplement of the complement of an angle is 132 degrees. What is the supplement of the angle?
PLEASE ANSWER AS MANY AS POSSIBLE AND IF U CAN TELL ME HOW TO DO IT. I NEED TO KNOW THIS STUFF FOR FINALS TOMORROW DONT GIVE ME A LINK TO A WEBSITE PLEASE. JUST PLEASE TRY 2 HELP!!!

1. Ok, think about the clock as 12 hours. The whole clock is 360 degrees. Thus, 360/12 = 30 degrees/ hour. So, 155 minutes = 2 hours 35/60 minutes. So, 155/60 x 30 degrees = 77.5 degrees.
2. Maybe. It depends on the Theorem. (I'm guessing that is a True/False question, the answer would be "False")
3. The arithmetic mean = (a + b) / n =( 18 + 50 )/ 2 = 34
The geometric mean of two numbers= square root of their product = square root(900) = 30. Thus, 3 The4-30=4
4. You can solve the degrees of each of the angles by setting up 3x + 4x + 5x + 6x = 360 you get 18x = 360, x =20 and degrees of 60,80,100,120. I don't know if that helps.
5. Ok. The supplement of the complement of an angle is 132 degrees. So, let that be angle x. The complement of angle x =
90 - x
The supplement of the complement, then, =
180 - (90 - x)
So, 132 = 180 - (90 - x). Solve for x to get x = 42.
The supplement of that is = 180 - 42 = 138.

I think the first one is 806 degrees......for the others I have no clue.
