A. In your own words, use 2-3 sentences to describe the special relationship between opposite angles when a quadrilateral is inscribed in a circle.

b. Quadrilateral ABCD is inscribed in the circle below.

Write an equation and solve for x.
Find the measure of all four angles. Find m⦨A, m⦨B, m⦨C, and m⦨D.
Explain your steps in solving the problem. Your explanation should include 2-3 sentences.

x = 40°

Angle A: 118°

Angle B: 120°

Angle C: 62°

Angle D: 60°

Step-by-step explanation:

When a quadrilateral is inscribed inside a circle, opposite angles add up to 180.

(x + 20) + 3x = 180

4x + 20 = 180

4x = 160

x = 40°

Angle A: 2(40) + 38 = 118°

Angle B: 3(40) = 120°

Angle C: 180 - 118 = 62°

Angle D: 40 + 20 = 60°

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.
