Question

three pins are inserted into a cork mat at points c, e, and d. the three pins are collinear. how much string is needed to reach from the pin at d to the pin at c then back to the pin at e? inches

Explanation:

Step1: Find length from D to C

The length from D to C is the sum of the lengths of DE and EC. Given EC = 1.1 inches and DE = 2.7 inches, so DC=2.7 + 1.1=3.8 inches.

Step2: Find total length

We need to go from D to C and then from C to E. The length from C to E is 1.1 inches. So the total length of string needed is 3.8+1.1 = 4.9 inches.

Answer:

4.9
