<u><em>The picture of the question in the attached figure</em></u>
The point P is the center of the circle (the drawing is not a scale )
step 1
Find the measure of angle ∠CPD
we know that
---> by supplementary angles (form a linear pair)

step 2
Find the measure of arc DC
we know that
<u><em>Central angle</em></u> is the angle that has its vertex in the center of the circumference and the sides are radii of it
so
----> by central angle
therefore

Answer:

or 4 and 5
The riddle given by Dr. Watson to Sherlock Holmes is:
217 is to 335
896 is to 543
345 is to ____
We need to find the missing number of the third pair of the riddle. This is a ratio and proportion problem.
217/ 335 = 896/ 543 = 345 / x
The value of x is 209.
Answer:
Step-by-step explanation:
y - y1 = m(x - x1) y1 = 1 x1 = 2 m = -1/3
y - 1 = -1/3(x - 2)
y = -x/3 + 2/3
