The CE beam divides the right angle DCM into two angles DCE and ECM. Find the degree measure of these angles if the DCE angle is 2/5 of the DCM angle.
It is known from the problem statement that the CE beam divides the right angle DCM into two angles, DCE and ECM. The DSE angle is 2/5 of the DSM angle. First, let’s calculate the degree measure of the angle DCE.
The right angle is always 90 degrees.
1) (90: 5) * 2 = 14 * 2 = 36 (degrees) – the degree measure of the angle DCE.
Now we can find the degree measure of the ECM angle.
2) 90 – 36 = 54 (degrees) – the degree measure of the ECM angle.
Answer: The degree measure of the angle DCE is 36 degrees, the degree measure of the ECM angle is 54 degrees.
