Given:
In the given circle O, BC is diameter, OA is radius, DC is a chord parallel to chord BA and 
.
To find:
The 
.
Solution:
If a transversal line intersect two parallel lines, then the alternate interior angles are congruent.
We have, DC is parallel to BA and BC is the transversal line.
[Alternate interior angles]
In triangle AOB, OA and OB are radii of the circle O. It means OA=OB and triangle AOB is an isosceles triangle.
We know that base angles of an isosceles triangle are congruent.
[Base angles of an isosceles triangle]
In triangle AOB,
Therefore, the measure of angle AOB is 120 degrees.
Answer:
15x^2-32x+9
Step-by-step explanation:
(3x – 1)(5x – 9)
FOIL
first: 3x*5x= 15x^2
outer: 3x(-9) = -27x
inner: -1(5x) = -5x
last: -1(-9) = 9
Add them together
15x^2 -27x-5x +9
Combine terms
15x^2-32x+9
Answer : C. Caplet form is the most expensive.
Tablet form comes in 50 mg tablets and cost $75.00 for a bottle of 100 tablets.
50 mg of 100 tablets so 50 * 100 = 5000mg
5000mg cost = $75.00
So 1mg of tablet form cost = 
= 0.015
Capsule form comes in 75 mg capsules and cost $63.75 for a bottle of 85 capsules
75 mg of 85 capsules, so 75 * 85 = 6375mg
6375mg cost = $63.75
So 1mg of Capsule form cost = 
= $0.01
Caplet form comes in 100 mg caplets and cost $70.00 for 40 caplets
100 mg of 40 caplets , so 100 * 40 = 4000 mg
4000mg cost = $70.00
So 1mg of Caplet form cost = 
= $0.0175
Caplet form is the most expensive.
