Answer:
45°
Step-by-step explanation:
The hour hand makes a trip of 360° around the face of the clock in 12 hours, so in 4.5 hours will make an angle of ...
... (4.5/12)·360° = 135°
clockwise from straight up.
The minute hand makes that 360° turn in 1 hour, so in 30 minutes, it will be 180° clockwise from straight up.
The difference between the angles of the hands is ...
... 180° -135° = 45°
2: Midpoint of segment AC is given as B3: Given4: Knowing that AC~=BC, AC~= DE
Looks like you have most of the details already, but you're missing one crucial piece.
is parameterized by
for and , and a normal vector to this surface is
with norm
So the integral of is
3x-9-5x = -7
combine like terms -9-2x = -7
add 9 to both sides
-2x = 2
divide both sides by -2
x - 2/-2 = -1
x = -1
