Vhich triangle's unknown side length measures 7 units?

The question is incomplete however the complete question is as follows:

Which triangle’s unknown side length measures 7 units?

A) A right triangle with a side length of 5 and hypotenuse with length .

B) A right triangle with a side length of and hypotenuse with length 5.

C) A right triangle with a side length of and hypotenuse with length .

Option A

Step-by-step explanation:

Pythagoras theorem can be satisfied by the length of the sides if the triangle is right angle triangle. The mathematical representation is as follows:

          Hypotenuse²= opposite² + adjacent²

According to the option :

Length of side = 5

Hypotenuse =

Then,

        = 5²+ adjacent²

         adjacent² = 74 - 25 = 49

         adjacent =

         adjacent = 7

Thus, the correct answer is option A.
