Question 1 of 10
What is the measure of JK?
A. 1250
B. 35°
C. 145
D. 550

A. 125°

Explanation:

Based on the angles of intersecting chord theorem, we have:

90° = ½(measure of arc NM + measure of arc JK)

Arc NM = 55°

Arc JK = ??

Plug in the value into the equation.

90° = ½(55 + JK)

Multiply both sides by 2

2*90 = 55 + JK

180 = 55 + JK

Subtract 55 from each side

180 - 55 = JK

125° = JK

JK = 125°

the value of the 4 in the hundreds place is 400 while the value of th e 4 in the tens place is 40

400 is way bigger than 40.
