Question

Please help me in finding the answer. Find x. (Congruent triangles)

Answer 1

`\Large \boxed{\sf 6.71 \ cm}`

Explanation:

The triangle is a right triangle. We can use Pythagorean theorem to solve for the hypotenuse.

a² + b² = c²

a and b are the lengths of the legs. c is the length of the hypotenuse.

6² + 3² = x²

Evaluate.

36 + 9 = x²

45 = x²

Take the square root of both sides.

√(45) = √(x²)

6.7082039325... = x

Answer 2

6.71cm

Explanation:

a²+b²=c²

6²+3²=x²

sqrt(6²+3²)=6.71
