Answer 1

So, what you’re doing here is basically finding the measurements of a right triangle, so we’ll use the formula

a^2+b^2=c^2

now, we plug in what we have

12^2+x^2= 19^2
144+x^2= 361

Bring the variable to one side by subtracting 144 from each side

x^2= 217

Square root each side to get rid of the exponent on the x

x= 14.7309

ANSWER:
15 inches
