Answer:
5.38
Step-by-step explanation:
A, 30. The triangle inside the circle is a perfect triangle (I mean it has three 60-degree angle ) so the angle POQ is 60degree, and since PQ is tangent to the circle at Q, the angle OQP is 90 degree, plus angle x, angle POQ and angle OQP formed a triangle, these three angle plus together should be 180 degree. You as a result would get 30
Greetings!
Option C would be correct.
3 + 4 + 5 = 13 therefore, C is the best answer.
Hope this helps!

Radical Equation:
1. Isolate the radical expression.
2. Square both sides of the equation: If x = y then x2 = y2.
3. Once the radical is removed, solve for the unknown.
4. Check all answers.
Another way of saying it:
1. Isolate the radical expression involving the variable. ...
2. Raise both sides of the equation to the index of the radical.
3. If there is still a radical equation, repeat steps 1 and 2; otherwise, solve the resulting equation and check the answer in the original equation.
