Answer:
The pink angle is half the angle subtended by the blue arc.
Step-by-step explanation:
Given
See attachment for circle
Required
Compare the pink angle to the blue arc
Let the pink angle be x and the angle subtended by the blue arc be y.
So, we have:
angle at circumference
angle subtended by arc
The relationship between x and y is:
Make x the subject
What’s the question?
If it’s area then the formula is pi r^2
If it’s the circumference then the 2pi r or pi d
3/4 ( (-50+2)/5)
= 3/4 ( -48/5)
= 3/4 * -48/5
= -36/5
Use the tens.Try 30x80. 76 rounds up to 80 and 33 rounds down to 30.
For a monic quadratic (factor of 1 on 
) we always add half the coefficient on the linear (
) term, so
Answer: 49/4
