HI this is my first post and it is regarding a question I have on MGMAT Flashcards.
I am currently going through the Geometry flashcards and came across a question that i can't seem to grasp. If you have access to the flashcards it is question 12/23.
I tried linking the image of the question below. Again, my first post, so i dont know if i did this correctly.
What I do not understand is that in the conclusion of the explanation it says angle PRQ is 60 degrees, but then the answer is that angle PRQ is 30 degrees? Am i missing something here? If this is the wrong forum please forward me to the correct forum.
thanks

Here is my attempt to answer the question.
Given angle PQO = 60 degree. Since PR is the diameter of the circle and O is the center of the circle. Therefore length of PO = PR = OQ = radius of the circle.
Also angle PQR = 90 degree and PQR is a right angled triangle.
Since PQO is 60 degree and PO = QO, therefore angle QPO is also 60 degree.
In the triangle PQR, angle PQR = 90 degree, angle QPR = 60 degree
Hence angle PRQ = 180 - (angle PQR + angle QPR)
angle PRQ = 180 -(90+60) = 30 degree.
-----------------------------------------------------------------------------------------------------------------------
The penultimate line in the flash card should read as
Therefore, angle QPR equals 60 degree, so angle PRQ = 180 degree - 90 degree - 60 degree = 30 degree.
