one side of the lot is made up of a vector with a magnitude of 55ft and a direction of 71 degrees , you need to find the perimeter and the measurements of all three angles .

step-by-step explanation:

the answer is c hope it

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

i hope this is what you were looking for.
