Plz its triangle properties and where using the 45º-45º-90º triangle theorem and the 30º-60º-90º triangle theorem.

The answer to your questions is below

Step-by-step explanation:

4.-

In a 45°-45°-90° triangle, the length of the legs are "x" and the length of the hypotenuse is x

Then, in this problem, the length of the leg is 7 then the length of the hypotenuse will be 7

5.- In a 30°-60°-90° triangle, the length of the hypotenuse is 2x, the length of the longer leg is x and the length of the shorter leg is x.

In this problem we have the length of the hypotenuse = 20 and find x.

                          2x = 20

                             x = 20/2

                             x = 10

          longer leg = x

6.- nonzero

7.- hypotenuse = 20 cm

     Find x

                         2x = 20

                           x = 20/2

                          x = 10

   Shoter leg = x = 10 cm

the 3rd option is right

step-by-step explanation:

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
