Answer:
11+3x=68
x=19
Step-by-step explanation:
11+3x=68 is your equation.
subtract 11 from both side to get 3x alone
3x=68-11
3x=57
divide 3 from both sides to get x alone
x=57/3
x=19
19 is your number.
Mhm, absolutely. Notice that we do not have a common unit circle value for any division of 8. But we do have a value for is 7pi/4. Now in order to actually get the value of 7pi/8, we use a half angle formula. So what we do is we will write out the formula and plug 7pi/4 into that formula, this will give us the value of 7pi/8. So the formula we need to plug 7pi/4 into is this:
<span>±<span><span><span>1+cos2θ</span>2</span><span>−−−−−−−−−</span>√</span></span><span>SO if you plug in 7pi/4 for theta in that formula, you think you could simplify it to find 7pi/8?</span>
