X=-1/3y+4/3 X=2Y+6 Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

jonny [76]

Both equal so set equal to each other
-1/3y+4/3=2y+6
times both sides by 3
-y+4=6y+18
add y to both sides and minus 18 both sides
-14=7y
divide both sides by 7
-2=y

sub back
x=2y+6
x=2(-2)+6
x=-4+6
x=2

Find the exact value using a sum or difference identity of cos 105°

mixas84 [53]

Answer:

Step-by-step explanation:

We can easily determine the exact value of this unknown angle by breaking it into known angles that can add together to give up 105. For example, 105 degrees is 60 + 45, both of which are found on the unit circle. We ill also use the trig identity for the sum of the cos of 2 angles which is:

$cos(60+45)=cos60cos45-sin60sin45$

These values are found on the units circle, so make sure you have one handy. Those values fill in as follows:

$(\frac{1}{2})(\frac{\sqrt{2} }{2})-(\frac{\sqrt{3} }{2})(\frac{\sqrt{2} }{2})$ which simplifies to

$\frac{\sqrt{2}-\sqrt{6} }{4}$
