Question

Determine the measurement of arc KJ.

mJK= how many degrees

Answer 1

Given: angle KMJ = 68.7°

To find:  measurement of arc KJ, ang MJK= ?

Solution:

• As we have given one angle: ang KMJ = 68.7°, so using this we can find the arc KJ by intercept formula.

• We know the formula of angle and intercept, that is:

             Angle KMJ = arc KJ/ 2

• So putting the given value in the formula we get:

• So, arc KJ = 2 (Angle KMJ)

                          = 2 (68.7°)

               arc KJ = 137.4°

(To find ang MJK, one more angle is needed.)

Answer:

      So, the measurement of arc KJ is 137.4°
