Given:
A circle with radius 7 units and chord CD = 7 units.
To find:
The measure of arc CD.
Solution:
Let O be the center of the circle.
In triangle OCD,
(Given)
(Radii of same circle)
(Given)
Since all sides are equal, therefore, the triangle OCD is an equilateral triangle.
Measure of each angle of an equilateral triangle is 60 degrees. So,
The measure of central angle is equal to the measure of corresponding arc.
Therefore, the measure of arc CD is 60 degrees.
Answer:
$8.40
Step-by-step explanation:
We can write a proportion to find the total amount last year using the information given. A proportion is two equivalent ratios set equal to each other.
We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
125(y)=100(10.50)
125y=1050
y=8.40
