Answer:

K=12

Step-by-step explanation:

First you know that what ever is being multiplied, it’s being done so by 4.

So you can divide the answer by the coefficient (the number in front of the variable. Which in this case is 4)

48 divided by 4 is equal to 12!

Answer:

m(∠C) = 18°

Step-by-step explanation:

From the picture attached,

m(arc BD) = 20°

m(arc DE) = 104°

Measure of the angle between secant and the tangent drawn from a point outside the circle is half the difference of the measures of intercepted arcs.

m(∠C) = $\frac{1}{2}[\text{arc(EA)}-\text{arc(BD)}]$

Since, AB is a diameter,

m(arc BD) + m(arc DE) + m(arc EA) = 180°

20° + 104° + m(arc EA) = 180°

124° + m(arc EA) = 180°

m(arc EA) = 56°

Therefore, m(∠C) = $\frac{1}{2}(56^{\circ}-20^{\circ})$

m(∠C) = 18°
