Determine the value of x using the information in the diagram.

Given:

Let us denote the intersection of the two chords be O.

Given that the measure of arc CD is 99°

The measure of ∠COD = 72°

We need to determine the measure of arc AB

Measure of arc AB:

Let us use the property that, "if two chords intersect at the interior of the circle, then the measure of each angle is one half the sum of the measures of the arcs intercepted by the angle and its vertical angle".

Using the above property, we have;

Substituting ∠COD = 72° , , , we get;

Multiplying both sides of the equation by 2, we have;

Subtracting both sides of the equation by 99, we get;

Thus, the value of x is 45°

Hence, Option B is the correct answer.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
