Please someone help I’m confused

7.21

Step-by-step explanation:

A^2+b^2=c^2 so 12^2+x^2=14^2 so 144+x^2=196 so 52=x^2 sqrt of 52 is around 7.21

7.21

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

12 ^2 + x^2 = 14^2

144 + x^2 = 196

Subtract 144 from each side

144-144 +x^2 = 196-144

x^2 = 52

Take the square root of each side

sqrt(x^2) = sqrt(52)

x =7.211102551

Rounding to the nearest hundredth

x = 7.21
