Question

PLEASE HELP ITS DUE TODAY FOR A GRADE!!!!

Answer 1

11

Explanation:

Find the length of the hypotenuse of the right triangle with sides 9 and 6

`a^(2) +b^(2) =c^(2) \\9^(2) +6^(2) =c^(2) \\81+31=c^(2) \\√(117) =c`

Use c and the height 2 to find the hypotenuse of the triangle with the dotted line

`√(117) ^(2) +2^(2) =c^(2) \\117+4=c^(2) \\221=c^(2) \\11=c`

the dotted line is 11
