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.

i believe the answer is:

-   william jennings bryan is a democrat while mckinley was a republican

at that time, the segment of population that choose for democratic party were the voters with low economic background and vice versa

- william jennings has support of populists and wants to have inflation to farmers while mckinley has support of bankers and businessmen , doesn't want inflation

the fixed value of gold make the large business able to stack up their gold without   being worried that it would devaluated.

- william jennings supported the silver standard while mckinley supported the gold standard

according to jenning, using other metal beside gold could the poor people to have more purchasing power and them advance in the society.
