Question

0 is about

Answer 1

You find the angle, you already have the opposite and adjacent. That angle is on a straight line with theta. Of course, a straight line, the two of them add up to 180 degrees.

Answer 2

tan90=16/12

Answer 3

It is not tan of 90. You are looking for the angle, you don't know what it is so call it alpha. tan alpha=16/12.\[\alpha =\tan^{-1} (16/12)\]alpha is tan inverse (16/12)

Answer 4

i got 53.13

Answer 5

Good so that angle is sharing a line with theta.\[\alpha +\theta =180 degrees\]

Answer 6

so i have to take away a and got answer

Answer 7

Yes

Answer 8

126.9

Answer 9

Good work.

Answer 10

i have two more problem
