a. 11.6 (rounded to nearest tenth)

b. Yes

Step-by-step explanation:

a²+b² = c²

6²+10² = c²

36²+100 = c²

136 = c²

√136 = √c²

11.6  = c

b. because 11.6 is the hypotenuse (longest side length) and there is 6 and 10 as the shorter leg lengths.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
