The sides of ΔABC are a, b, and c. If the lengths of a = 7 and b = 10, what are the possible lengths of c?

The possible lengths of c are between 3 to 17.

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

a = 7

b = 10

As we know that, in a triangle length of third side is always greater than difference between the given two side, and always lesser than sum of both side.

So, Difference between both side = 10 - 7 = 3

Sum of both side = 10 + 7 = 17

Hence, the possible lengths of c are between 3 to 17.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
