Complete Question

The complete question is shown on the first uploaded image

Answer:

The value of  y  =  122^o

The value of  x = 61^o

Step-by-step explanation:

Generally the total angle that make up a circle is

      \theta _T = 360

From the diagram we see that

    \theta _T  =  y^o + 238^o

=>    y^o  =  360  -238

       y^o  =  122^o

Generally angle that is formed as a result of interception of a chord and a tangent is equal to the intercepted arc divided by 2

 This implies that

           x =  \frac{y}{2}

substituting values

          x =  \frac{122}{2}

          x = 61^o

If f(x) = 4x²-2 then f(-2) is​
klemol [59]
To find f(-2), substitute (-2) into x of the function f(x) = 4x^2-2
We get, f(-2) = 4(-2)^2 - 2
= (4*4)-2 = 16-2 = 14
Therefore, f(-2)=14.
