Cos(x-30°)=0 <br> how???????????????

lesya [120]

Answer:

Step-by-step explanation:

I'm assuming you're trying to solve this for x. We use the difference identity for cosine and rewrite:

$cos(x-30)=cosxcos30+sinxsin30$ and simplify using the unit circle to help.

$cosx(\frac{\sqrt{3} }{2})+sinx(\frac{1}{2})=0\\cosx(\frac{\sqrt{3} }{2})=-\frac{1}{2} sinx\\cosx=-\frac{1}{2}(\frac{2}{\sqrt{3} })sinx\\cosx=-\frac{1}{\sqrt{3} }sinx\\1=-\frac{1}{\sqrt{3} }\frac{sinx}{cosx}\\1=-\frac{1}{\sqrt{3} }tanx\\-\sqrt{3} =tanx$

and on the unit circle, the angle where the tangent is negative square root of 3 is -60° which is also a positive 300°

Find the 55 term of the arithmetic sequence 2,-18,-38

ivanzaharov [21]

Answer:

-1098

Step-by-step explanation:

Sense the sequence is subtraction 20 each time we will subtract 3 from 55 since 3 numbers are already up there.

Now multiply 20 by 53

20 x 56= 1060

Now subtract 1060 from -38

-38-1060= -1098
