Answer:
135 degrees
Step-by-step explanation:
2π radians is the central angle of a full circle, so 2π radians is 360 degrees.
That means that π radians = 180 degrees.
3π/4 radians * (180 degrees)/(π radians) = 135 degrees
3 1/2
Becase if you turn them both in to inporper fractions then you can do other sh1t to find it out
Put the top point on the first point from the top and the other one on the first point from the bottom.
