Question

Question 1: Find the value of angle K.

A.) 120°

B.) 140°

C.) 80°

D.) 100°

Question 2: Identify the value of x and the length of each chord.

A.) x = 9.1; AB = 16.5; CD = 14.1

B.) x = 11.5; AB = 16.5; CD = 16.5

C.) x = 9.5; AB = 16.5; CD = 14.5

D.) x = 9.1; AB = 9.1; CD = 16.5

Please give explanation and answer!

Answer 1

The opposite angles are supplement.

9c - 3 + 5 (c + 3) = 180

Solve for c

K = 10 * c =120

Intersecting cord theorem is a * b = c * d

5 * x = 13 * 3.5

Solve for x

For AB, just add AE + EB and for CD, add CE and ED
