Why is each statement correct, since none of them

suffies to answer the question?

Hi all,

I need some help with this question?
Why according to the book, it says that each statement is sufficient, since you cannot answer whih angle is greater from any of them?
May be they mean to say that each statement is not sufficient to answer, therefore easch one is correct?

Problem is too easy and simple to bother you with it.

I am so sorry!

Phew its difficult to answer such Qs with the font that you have put in.

Both are sufficient. This is why.

You need to find how mPRS - mPQR = ?

In both cases use the following rule:

sum of a exterior angle of a triangle is equal to sum of the two remote interior angles.
