Question

find the perimeter of a right triangle with legs that measure 5 cm and 9 cm, round to the nearest tenth.

Answer 1

perimeter = side + side + side

Answer 2

now find the unknown side using pythagoras theorem

Answer 3

sqrt{5^2+9^2}=unknown side

Answer 4

sqrt{25+81}
sqrt{106}

Answer 5

first of all tell me is there hypotenuse unknown

Answer 6

???

Answer 7

i typed the only information given to me.

Answer 8

you're actually supposed to solve for the hypotenuse

Answer 9

how do i do that?

Answer 10

what formula do i use?

Answer 11

A62=B62=C^2
5^2+9^2=C^2
25+81=C^2
C^2=106
C=SQRT106
C=10.3
5+9+10.3=24.3 ANS. FOR THE PERIMETER.

is this right?

Answer 12

right

Answer 13

thank you
