The sides of a square are all the same therefore you should multiply 2 1/2 * 4 = and get 10.

Ac=r+d for a solve equation for the indicated variable
konstantin123 [22]

\boxed{a=\frac{r+d}{c}}

<h2>Explanation:</h2>

Here we have the following expression:

ac=r+d

And the question asks for solving the equation for the variable a. So we need to divide both sides of the equation by c:

ac=r+d \\ \\ \frac{ac}{c}=\frac{r+d}{c} \\ \\ \\ But: \\ \\ \frac{c}{c}=1 \\ \\ \\ So: \\ \\ \boxed{a=\frac{r+d}{c}}

Find the values of x and y. lines that appear to be tangent are tangent
Ket [755]

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
