Answer:
x =14.73
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2 + b^2 = c^2 where a and b are the sides and c is the hypotenuse
12^2 + x^2 = 19^2
144 + x^2 =361
Subtract 144 from each side
144-144 +x^2 =361-144
x^2 =217
Take the square root of 217
x = sqrt(217)
x =14.73
x + (-4) = 10.
We can use the positive - negative rule.
x + (-4) = 10.
x - 4 = 10.
x = 10 + 4
x = 14.
The numerical expression is x+4/3
