4 * side^2 = diagonal1 ^2 + diagonal2 ^2
4 * side^2 = 12^2 + 16^2
4 * side^2 = 144 + 256
4 * side^2 = 400
side^2 = 100
side = 10
So the perimeter = 4*10 = 40
In geometry, the angle bisector<span> theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite </span>angle<span>. It equates their relative lengths to the relative lengths of the other two sides of the triangle.
so the answer is B</span>
Answer:
b=-108
Step-by-step explanation:
To solve this equation for b, you simply multiply each side by 18. The reason you do this is to isolate the b.
