Question

Which is the best estimate of the angle?
40
75
105
140

Answer 1

any ideas?

Answer 2

40?

Answer 3

This a right angle (90) so if that one is smaller the answer can't be bigger then 90.

Answer 4

yes either that or 75

Answer 5

since both are less than 90

Answer 6

40 right?

Answer 7

but if you carefully draw it out, you'll see that it's roughly half of that right angle drawn above

Answer 8

and since 40 is close to 45 (which is half of 90), I'd go with 40 as well

Answer 9

heres a picture

Answer 10

wouldnt that be 75
