Mathematics

Step-by-step explanation:

let y = f(x)

y = 2x/7 + 4

2x/7 = y - 4

x/7 = (y - 4)/2

x = 7(y - 4)/2

therefore, f^-1(x) = 7(x - 4)/2 (Option A)

If f(x)=2x+4 then the inverse is x=(2/7)f(x)+4
Now just solve for the new f(x)
(2/7)f(x)=x-4
f(x)=(7/2)(x-4)

As you can see, angle 5 and angle 6 are supplementary.  And angle 5 and angle 3 are congruent because they are alternate interior angles.  

So it will be
x+2 = 180- x+3 
                         move x over from the right to the left
2x+2 = 183
                         move 2 over from the left to the right
2x = 181
                          divide by 2
x= 90.5

and angle 3 and angle 1 are vertical angles so they are congruent.  Using the angle 3 formula to solve for the answer:

90.5+3 =93.5

When angles are congruent, their measures are congruent, therefore, measure of angle 1 is 93.5
