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
