Find the value of x, do not round until the final answer.

thank you!​

Step-by-step explanation:

Draw a line from the center of the circle O to the end of either side of the line marked as 4. This line represents two things:

In this case, both are important. Since is also a radius of the circle, the line must be equal to , since all radii of a circle are equal. To find the length of this line, use the Pythagorean Theorem:

, where is the hypotenuse of the triangle and and are the two legs of the triangle.

Since we're solving for the hypotenuse and the two legs are 5.1 and 2, we have:

(round as necessary).

b. x- 48 =120
