Question

calculate the unknown side (x) of the triangle shown below. Give your answer to one (1) digit after the decimal.

Answer 1

If that angle is 90 degrees, then you should use the pythagorean theorem of right triangles to find x.

Answer 2

Using the Pythagorean theorem in a right triangle, the hypotenuse squared is equal to the sum of the squares of the remaining sides. In your case, A=21, B=13, and C=x. Pythagorean Theorem states \[A^2+B^2=C^2\].

Answer 3

a^2+b^2=c^2

Answer 4

\[21^{2} + 13^{2} = z^{2}\] by pythagorean theorem

Answer 5

oh okay guys got it

Answer 6

x=610 wich is equal to 24.70 correct?

Answer 7

Did you just write 610 = 24.70? If you mean the Square Root of 610 is close to 24.70, that that is much more sensible.

Answer 8

610 i s close to 24,70
