Answer:
Since,



1)

2) 
Differentiating w. r. t x,

3) 
Differentiating w. r. t. x,

4) 
Differentiating w. r. t. t,

5) 
Differentiating w. r. t. p,
6) 
Differentiating w. r. t. t,

7) 
Differentiating w. r. t. y,

AB + C
= (x + 1)(x^2 + 2x - 1) + 2x
= x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x
= x^3 + 3x^2 + 3x - 1

Answer:
27.8 degrees
Step-by-step explanation:
Wasn't it 'a,' not 'A,' that you wanted?
The ratio a/ 30 is the cosine of the angle 22 degrees, which in turn is 0.927:
a
Then 0.927 = ------- which yields a = 30(0.927) = 27.8 degrees
30
