Question

given jkl, use the protractor to measure ∠jkm and ∠lkm. also determine the sum of two angle measurements. move the protractor using the central blue dot. rotate / scale the protractor using the green dot. you may shift or zoom the canvas using your mouse.

Explanation:

Step1: Measure ∠JKM

Place protractor center at K, align base - line with one side of ∠JKM, read degree measure. Let's assume ∠JKM = 40°.

Step2: Measure ∠LKM

Place protractor center at K, align base - line with one side of ∠LKM, read degree measure. Let's assume ∠LKM = 30°.

Step3: Calculate sum

Add the two angle - measures: 40°+30° = 70°.

Answer:

The measure of ∠JKM is assumed as 40°, the measure of ∠LKM is assumed as 30°, and the sum of the two angle - measures is 70°.
