Question

Determine the length of the unknown sides in the triangle below. State your answers correct to decimal

place.

Answer 1

x=9.89

Explanation:

since both missing sides are equal, we give length x to both.

then, using the Pythagorean theorem, a²+b²=c², we get:

x²+x²=14²

we aolve for x:

2x²=14²

x²=14²/2

x=sqrt(14²/2)=9.89
