Answer:

Step-by-step explanation:

<u>differentiating numerator wrt x :-</u>
(sinx)' = cos x
<u>differentiating denominator wrt x :- </u>
(1 + cos x)' = (cosx)' = - sinx
- Let's say the denominator was "v" and the numerator was "u"

here,
- since u is the numerator u= sinx and u = cos x
- v(denominator) = 1 + cos x; v' = - sinx


since cos²x + sin²x = 1

diving numerator and denominator by 1 + cos x

Answer:
<h2>
D.84</h2>
Step-by-step explanation:
<u>*It's an isosceles triangle so 2 of the angles are going to be the same degrees</u>
<u>*Every triangle is 180 degrees</u>
(48)+(48)=96 then 180-96=84
