Differentiate both sides with respect to <em>x</em>, using the chain rule for the sine term:
Solve for d<em>y</em>/d<em>x</em> :
Answer:
Twelve-fifths.
Step-by-step explanation:
The diagram is shown below
Given triangle be right angled at 
,
Withe reference to 
,
Its opposite side is 
, adjacent side is 
and hypotenuse is 
We are to find the value of 
We know 
Substituting the above values we get,
So the answer is Twelve-fifths.
Always divide by 10 first, for example; if it was 10% of 20 you would divide 20 by 10 to get 2. If it was 20% of 40 you would divide by 10 to get 4 then times by 2 to get 8.
Answer:
x = 14
A = 38
B = 71
C = 71
Step-by-step explanation:
Since we have a triangle, the addition of the measure of all the measure of the angles give 180
Thus;
3x-4 + 5x + 1 + 7x-27 = 180
15x-30 = 180
15x = 180 + 30
15x = 210
x = 210/15
x = 14
To get the measure of each of the angles, we substitute for x
A = 3x-4 = 3(14) - 4 = 38
B = 5x + 1 = 5(14) + 1 = 70 + 1 = 71
C = 7x - 27 = 7(14) - 27 = 98-27 = 71
