solomonzelman · Answer

at first, angle 67, is which of the angles of the triangle ?

solomonzelman · Answer

You aren't taking any effort, but I am still giving you a very good hint...

proportions of the sides of the  " 30-60-90 triangle "  are  b, b√3 and 2b , respectively.
So, the side NO is twice less than hyp, but, it's even less than twice less than the hyp because the smallest angle that forms NO is less than 30 (not actually 30) .

20 is not even nearly god to be 1/2 of 100, or to be 50.
