Question

-200(tan(30)) / (tan(30) - tan(60))=100
The key is: 100, but my caculator answer 200, can some one help me how to use caculator for answer is: 100.

Answer 1

i got 100, solve the numerator first, save the result. then solve the denominator. then divide the numerator by the denominator

Answer 2

-200 tan30= -115.47
tan30 - tan60 = -1.1547
so the final result will be -115.7/(-1.1547) = 100

Answer 3

thank
