Answer:
The picture is not clear.
E) sqrt(30)
This is a nice problem. It was helpful to read the topic at the top.
Notice that the two right triangles are similar. Their sides are in proportion.
That is the side '3' is what 'x' is in the other triangle (you need to rotate it!)
Then 'x' is similar to '10'
3/x=x/10 ---> x^2=30, x=sqrt(30)
If you are patient, you can check that for sqrt(30) pythagoras theorem works for all the triangles.

Answer:
D
Step-by-step explanation:
Answer:
A. 3rd equation
B. 1st equation
C. 4th equation
D. 2nd equation
The final value within the square root can't be negative or else the solution is imaginary, and you also cannot divide by a value of zero.
Answer:
A. 
Step-by-step explanation:
We have been given a diagram. We are asked to find the measure of angle RST.
We can see that angle RST is formed by intersecting chords inside the circle, so its measure would be half the sum of intercepted arcs as:
Therefore, the measure of angle RST is 62 degrees.
