Answer:
<h2>m
F = 34°</h2>
Step-by-step explanation:
If E and F are complementary I means that the sum of their angles add up to 90° since all complementary angles have the sum of their angles equal to 90°
To find mF add mE and m F and equate it to 90 to find x then substitute it into the expression for mF
Thats
mE + mF = 90
9x - 38 + 2x + 40 = 90
11x + 2 = 90
11x = 90 - 2
11x = 88
Divide both sides by 11
x = 8
Now we have
if m F = 9x - 38
m F = 9( 8) - 38
mF = 72 - 38
We have the final answer as
<h3>m
F = 34°</h3>

because 24 divided by 3 is 8 and that times 6.33 is $50.64
Answer:
Step-by-step explanation:
The zeros of the function can be found by factoring. Since this has already been started with completing the square, we will just pick up from where it was left and finish factoring. Set the quadratic equal to 0 first.
then move over the 9:
"undo" the squaring by square rooting both sides to get
x - 8 = ±3. And then add over the 8 to get the solutions
x = 8 + 3 and x = 8 - 3. The solutions, then, are
x = 5 and x = 11
Expression one is twelve.
