Answer 1

15^2 + 9^2 = c2

Answer 2

careful!

Answer 3

?

Answer 4

this time, the hypotenuse = 15 = c

Answer 5

o

Answer 6

O, I c

Answer 7

a^2 + 9^2 = 15^2?

Answer 8

exactly :)

Answer 9

o

Answer 10

Where does the A go?

Answer 11

we try to solve for a

we want to know what a = ?

Answer 12

o

Answer 13

So its Like this then, 9^2 + 15^2 = a^2

Answer 14

To make it in a Simpler Format

Answer 15

not quite

a^2 + 9^2 = 15^2

subtract (9^2) from both sides
so

a^2 = 15^2 - 9^2

Answer 16

O

Answer 17

a^2 = 225 - 81

Answer 18

a^2 = 144

Answer 19

144 in a Square Root will be 12 Cm. :D

Answer 20

yup!

Answer 21

Ye!
