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

Suppose someone tells you that she has a triangle with sides having lengths 2.2, 4.5, and 6.7. Is this a right triangle?
laila [671]
You can apply the Pythagorean theorem:
a^2 + b^2 = c^2
c is the longest side of the triangle
2.2^2 + 4.2^2 = 6.7^2
4.84 + 17.64 = 44.89
22.48 =/= 44.89
That is not a right triangle

For example, 48/64 is equivalent to 72/96, both have the value of 3/4. </span>
