Determine the value of x

x = 10

Step-by-step explanation:

Since these angles are vertical angles, we know that 40 = 3x + 10. Subtract 10 from both sides to get 30 = 3x. Divide both sides by 3 to get x = 10.

Just putting values that would come in blanks

Blank 1 = f(x)

Blank 2= x

Blank 3= 4

Blank 4= 0

Step-by-step explanation:

We need to find inverse of function

To find inverse put y for x and solve for x

i.e

Now solve to find value of x

Taking square on both sides

Now put f⁻¹ (x) in place of x and replace y with x

So, Blank 1 = f(x)

Blank 2= x

Blank 3= 4

Blank 4= 0
