PLEASE HELP. BEST ANSWER GETS BRAINLIEST. Find x in the following right triangle

12 dm

Step-by-step explanation:

Use the Pythagorean Theorem to find the missing length of the right triangle:

We are given the hypotenuse's length of 13 dm, and a leg length of 5 dm.

Let the missing leg be 'b':

The missing side length should be 12 dm.

12 dm

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + x^2 = 13^2

25 + x^2 =169

Subtract 25 from each side

x^2 = 169-25

x^2 = 144

Take the square root of each side

sqrt(x^2) = sqrt(144)

x = 12

the answer will be b x² +x-1
