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

Since it's a right triangle, you can use Pythagorean theorem to find the hypotenuse. a^2 + b^2 = c^2
So it would be 15^2 + 15^2 = c^2
225+225=c^2 /450=c
21.21=c
Now just find the perimeter and you'll get the answer to your question above.
