Hey!
-------------------------------------------------
Solution:
9 + 22 = x + 1
9 + 22 - x = x + 1 - x
31 - x = 1
31 - x 31 = 31 - 1
x = 30
-------------------------------------------------
Answer:
x = 30

Hope This Helped! Good Luck!
C.
This is because the x vale is clearly after the 6 and the y value is right on 5
Angles B and D are congruent so:
(360-112-74)/2=87°
Answer:

Step-by-step explanation:
We need to add the two terms.

Solving,
Combine the like terms and adding those terms

So, the answer is:

D over dx (x sin^2(x)) = sin(x) (sin(x) + 2 x cos(x))
