20) A triangular garden has sides that

5
6- 7
feet.
6
What is the perimeter of the garden?

Since all the three sides of the triangle are of equal length, we can find the perimeter by multiplying the length of each side by 3. 20 + 20 + 20 = 3 × 20 = 60 cm.

i belive those are the ones that are under 90 degreese.

you can't solve x because it is 2 linear equation and you only have one equation
