Question

Calculate the unknown side x for each triangle below. 3^2+x^2=6^2



a. b.

Answer 1

\[b^2=c^2-a^2\]

Answer 2

just substitute b with x

Answer 3

then look for the value of b

Answer 4

@panlac01 let me draw the pic for U

Answer 5

are we talking about a right triangle here?

Answer 6

okay, use the pythagorean theorem

Answer 7

\[a^2+b^2=c^2\]

Answer 8

let 6 be the a, 3 be the b and x be the c

Answer 9

are you sure? according to the equation, the hypotenuse of triangle should be 6

Answer 10

@dumbcow and @panlac01 so is it 3^2+x^2=6^2 or 6^2+3^2=x^2

Answer 11

the latter

Answer 12

if we followed your drawing then it is the latter

Answer 13

According to your drawing:

\[\color{red}{x^2 = 6^2 + 3^2}\]

Answer 14

@panlac01 ok so I got 45-x^2=0
