Question

(8x-5) (2x) (3x-10). what is the largest angle??

Answer 1

(3x)2(7= 42 the largest angle is (8x-5)

Answer 2

8x-5 would be the largest angle because as you approach a larger and larger x value, 8x-5 will skyrocket past the other two. Also when you plug in a low value like 1, 8x-5=3, which is still higher than the other two. The only exception is if you plug in a negative x value which is impossible.
8x-5
