I need a picture in order to help
Here is a picture of a bobcat anyway
It should be 105 because it’s equal
<u>Given</u>:
The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)
The points are rotated 90° about the origin.
We need to determine the coordinates of the point C'.
<u>Coordinates of the point C':</u>
The general rule to rotate the point 90° about the origin is given by

Substituting the coordinates of the point C in the above formula, we get;

Therefore, the coordinates of the point C' is (-1,2)
Answer:
Part a) 
Part b) 
Step-by-step explanation:
step 1
we know that
The diameter of the circle divide the circle into two equal parts
so
PM=MQ
Applying the <u>Intersecting Chord Theorem</u> (When two chords intersect each other inside a circle, the products of their segments are equal)


we have


substitute



step 2
Find the value of PQ
we know that

so


we have

substitute

Answer:
Step-by-step explanation:
c.r.=6/12=1/2
