Answer:
The Value of Angle CFD is 105°
Step-by-step explanation:
As you mentioned in the question, Triangle DEF is an isosceles triangle so angles DEF and DFE have the same degree value. If Angle DEF measures 75° then Angle DFE measures 75° as well.
A straight line has an Angle of 180°. Seeing as how CFE is a straight line and Angle DFE is 75°. We can subtract 75° from 180° in order to get the Angle CFD.
So the Value of Angle CFD is 105°

Exponential functions are related to logarithmic functions in that they are inverse functions. Exponential functions move quickly up towards a [y] infinity, bounded by a vertical asymptote (aka limit), whereas logarithmic functions start quick but then taper out towards an [x] infinity, bounded by a horizontal asymptote (aka limit).
If we use the natural logarithm (ln) as an example, the constant "e" is the base of ln, such that:
ln(x) = y, which is really stating that the base (assumed "e" even though not shown), that:
if we try to solve for y in this form it's nearly impossible, that's why we stick with ln(x) = y
but to find the inverse of the form:
switch the x and y, then solve for y:
So the exponential function is the inverse of the logarithmic one, f(x) = ln x

Answer:
A and B
Step-by-step explanation:
Because the surface area is
BA is the base, so also works.
