Process is very important for DS. Though math knowledge is necessary it is not sufficient :) to succeed on DS.
If one has a clear process than most DS problems can be approached similar to a regular math problem.
I think the answers are B and E, respectively.

Good post!

I agree with Abhij on the Answers B and E. Can we get the answers?

1st question : B is suff because we need to know that where the line is tangent to the circle and A only says that it passes through this point which could or could not be on the circle.

2nd question: E we do no know what sides are being represented hypotenuse or not.

Yes, the answers are correct. The first one is (B) and the second one is (E)

It is, in fact, the same article. Notice the last line of the article in the post: "~Article written by Brian Galvin, Veritas Prep"

Ok, think about what is given: J is tangent to the circle. The circle is centered at the origin.
Statement 1: J runs through (5, 5)

Here are two cases where all this information is used but the slope of the tangent is different.

Hi Karishma,

Can you help me to clarify why the 2nd statement is sufficient (1st question)?
since we are looking to calculate the slope and we only have one coordinate with the 2nd statement.

Thank you ..
