Question

Find the length of the third side. If necessary, round to the nearest tenth.
15
9

Answer 1

Answer:

12

Step-by-step explanation:

a^2+b^2=c^2

9^2+b^2=15^2

81+b^2=225              subtract 81 from both sides

b^2=144                     square root b^2 and 144

b=12

Hope this helps :)
