It is either A or D, but I think it’s A
I think you would put 570 in the blank since 19 x 3 = 57
Answer:
The hour hand of a clock moves -66* in 2 1/5 hours.
Step-by-step explanation:
2 x -30 = -60, and 1/5 of -30 is -6, and -60-6=-66 degrees.
The angles when added equal180
therefore:
x+x+(x+45)= 180
3x+45=180
3x=180-45
3x=135
x=135/3
x=45
therefor the angles
are 45, 45, 90 degrees
