Answer 1

im having difficulty with this question

Answer 2

hint: use this identity

\[\Large \tan(x-y)=\frac{\tan(x)-\tan(y)}{1+\tan(x)\tan(y)}\]

Answer 3

Both planets and stars can be seen in the night sky. What is the main difference in the light we see from the planets and the light we see from the stars?


A. The light from the planets is reflected light from the Sun and the light from the stars is actually produced by the stars.

Answer 4

oh ok, so you just solve for the bracket inside right?

Answer 5

in this case,

x = 170
y = 110

Answer 6

ok so it'll be tan (60)

Answer 7

ok now i just use special angles, ty man

Answer 8

yes, then evaluate that
