Short Answer

Expert verified

The answer ism鈭�3+m鈭�4=m鈭�A

Step by step solution

01

Step 1. Observe the diagram.

From the given figure, it is observed that 鈭�DAL=m鈭�3and 鈭�DAE=m鈭�4.

02

Step 2. Description of step.

Since, 鈭�LAS=m鈭�Asuch that 鈭�LAS=鈭�DAL+鈭�DAE.

03

Step 3. Calculate m鈭�3m+鈭�4=m鈭�?

In order to find m鈭�3+m鈭�4, substitute m鈭�3for 鈭�DALand m鈭�4for 鈭�DAEinto 鈭�LAS=鈭�DAL+鈭�DAE.

鈭�LAS=鈭�DAL+鈭�DAE=m鈭�3+m鈭�4m鈭�A=m鈭�3+m鈭�4

Therefore, m鈭�3+m鈭�4=m鈭�A.
