Your denominator is going to be 4 digits. "18,18,18,18".
A point has D) zero dimensions
(x-2) + (x-1) + x + (x+1) + (x-2) + (x+3) = 447
6x + 3 = 447
6x = 447 - 3
6x = 444
x = 444/6
x = 74
P/9 = 90
Multiply 9 to 90 to isolate the variable.
P = 9 x 90
P = 810
A 30-60-90 triangle is special because of the relationship of its sides. Also <span>It turns out that in a 30-60-90 triangle, you can find the measure of any of the three sides, simply by knowing the measure of at least one side in the triangle.
Hope this helps. :)</span>
