Whata the answer for this pythagorean theorem?

To do this we must rearrange the original pythagorean theorem formula...

Now, we need to input the given numbers into our new formula...

Alright, now that we have done that lets find out what 5² and 4² equals...

Now that we have done that we need to subtract 16 from 25...

We need to find the square root of our answer (9) to get our final answer.

The square root of 9 equals 3. Thus, our final answer is B, x=3.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
