Q. In the circle below, IK is a diameter. Suppose m \overparen{J K}=102^{\circ} and m∠KJL=54∘. Find the following.(a) m∠IJL=(b) m∠IKJ=
Identify Relationship: Identify the relationship between the diameter and angles in a circle.Since IK is a diameter, angle IKJ is a right angle (90 degrees) because an angle inscribed in a semicircle is a right angle.
Calculate Angle: Calculate m/IKJ using the property of the right angle.m/IKJ=90 degrees.
Use Exterior Angle Theorem: Use the given measure of the arc and the Exterior Angle Theorem.mJK◯=102∘, which is the measure of the arc formed by points J, K, and L. The exterior angle, m∠KJL, is given as 54∘.
