Question

Use the pythagorean theorem to determine the length of the unknown side, the perimeter and the area of the triangle. 13 inches, 5 inches, and A

Answer 1

Are we given the hypotenuse or not?

Answer 2

Leg 2 Plus Leg 2 = Hypotnuse ^2

Answer 3

Leg ^2 plus Leg ^2 = Hypotenuse ^2

Answer 4

yeah but the 13 could be the hypotenuse or a leg. it matters.

Answer 5

13 is the hypotenuse

Answer 6

The leg is 5 in

Answer 7

\[A^2+b^2=c^2\]
\[A^2+5^2=13^2\]
\[A^2=13^2-5^2\]
\[A^2=144\]
\[A=12\]
Therefore the Area
\[=\frac{ 12\times5 }{ 2 }\]
\[=30 inches^2\]
Perimeter
\[=5+12+13\]
\[=30inches\]
