Answer:
x = 110
Step-by-step explanation:
all angles of the triangle MUST add up to 180 degrees.
45 + 65 = 110
180 - 110 = 70
since x is sittling on a 180 degree angle, the sum of 70 and x must equal 180 too
180 - 70 = 110
I think it’s c sorry if I’m wrong

Find the derivative of
First, differentiate it by applying the product rule:
where
As
u is a composite function, then you have to apply the chain rule to evaluate its derivative:
Substitute back for
and then substitute back for
Subsitute

Answer:
The last one.
Step-by-step explanation:
I think it's the last one because as x increases by one, y increases by a constant rate of 5. The others don't increase by a constant rate. (I don't know if this is right but I think it is!)
