Question

Jolene is putting trim around the edge of a triangle head scarf. The scarf from a right triangle with legs that measures 15 inches each. Find how much trim Jolene needs to the nearest tenth of an inch

Answer 1

Since it's a right triangle, you can use pythagorean theorem to find the hypotenuse. a^2 + b^2 = c^2

Answer 2

So it would be 15^2 + 15^2 = c^2
225+225=c^2
/450=c
21.21=c
Right?

Answer 3

Exactly! Since you have now identified all three sides, you can now find its perimeter!

Answer 4

Thank you. :)
