No; the tangent ratio only deals with the lengths of the opposite side and adjacent side. You can square the two sides and add them together, then find the square root of the sum to find the length of the hypotenuse.

Use tangent to find the other leg, and the sine or cosine to find the hypotenuse.
Using the mathematical principles of trigonometry, you will need to know the lengths of any two of the sides of the right-angled triangle in order to calculate the other angles. The ratios of the lengths can be looked up in tables (or a scientific calculator may be used) to find the angle. The three sides of a right angled triangle have names as follows:- Hypotenuse - the longest side of the triangle, opposite the right angle Adjacent - the side next to the angle you wish to know Opposite - the side opposite the angle you wish to know The ratios are named as follows:- Sine - ratio of length of Opposite divided by length of Hypotenuse Cosine - ratio of length of Adjacent dived by length of Hypotenuse Tangent - ratio of length of Opposite divided by length of Adjacent These can be remembered by the mnemonic SOH CAH TOA Depending on which sides have the known lengths, calculate the ratio and look up the value for the angle in the Sine, Cosine or Tangent table as applicable. Once the value for one angle is known, the value for the other angle is 90 minus the value of the known angle.
Sine ratio = opposite/hypotenuse
Sides have lenght, angles do not. Cosine is the ratio of the adjacent side to the hypotenuse. Cosine can be used to find either of these sides if the other is known.
Use tangent. Your equation will be tan(slope of hypotenuse) = opposite side / adjacent side. it's easier if you just do A squared plus b squared equals c squared. Then subtitute the numbers gived in.
