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

6.71cm

Step-by-step explanation:

a²+b²=c²

6²+3²=x²

sqrt(6²+3²)=6.71

Step-by-step 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

The answer is A.

23-22=1

1÷23=0.0434782609

Convert : 0.0434782609 to a percent

which would be 4.34% which would be

rounded to 4.3%.
