Add the three angles and set them to 180
4x-13+15+x+18=180
5x+20=180
5x=160
x=32
Then plug in to get A and C
A=4*32-13
A=115
C=32+18
C=50
Answer:
see explanation
Step-by-step explanation:
Differentiate using the product rule
Given y = f(x)g(x), then
= f(x). g'(x) + g(x). f'(x)
here f(x) = 
⇒ f'(x) =
g(x) = cosx ⇒ g'(x) = - sinx
Hence
= (- sinx) + cosx
= cosx - sinx
Conversion from milliliters to ounces can be done using the following relation: 1 mL = 0.033814 ounce.
Given 570mL, we multiply it to the amount of ounces as shown in the relation. This is done below:
570 mL * (0.033814 oz / 1 mL) = 19.274 oz
I think it’s either b or c
