Answer:

38°

Step-by-step explanation:

a whole circle is equal to 360 degrees so if 52 +90= 142 the opposite side also equals 142 because they are clearly the same size. ED and AB are also the same sizes. if 360- (142+142) = 284. then you will have to divide 284 by 2. so 284÷2=76 and 76÷2=38°

hope you understand, I not that good at explaining things

also I don't know what the m means in mED

Answer:

g(f(x)) = x

Step-by-step explanation:

You are given f(x) = -4x - 1 and g(x) = $\frac{x+1}{-4}$ . Keep in mind that f(x) or g(x) is the same as a y = equation, but two separate equations.

You are trying to find g(f(x)), which means that you will use f(x) and substitute this value into the x value in the equation of g(x).

It will look like: g(-4x - 1) = $\frac{x+1}{-4}$

$\frac{(-4x-1)+1}{-4}$

Now evaluate the expression to solve the problem. Start by combining like terms.

$\frac{(-4x)}{-4}$

You are left with -4x/-4. We can simplify this even further by dividing both sides of the fraction by -4/-4. The -4's cancel out and become 1's, so you are left with:

$x$
