Hi everyone! I’m trying to make sure I understand what this question is getting at. If they had (hypothetically) told you that angle PSQ was a right angle, what could we then conclude about the triangles (other angles, side length, similarity, etc)?

Thanks!

No, even then it wouldn’t be correct

Imagine an equilateral triangle and draw the height

The height divides the base in two equal halves and meets it at 90 degrees

But still, x = 30, where as y = 60 in it

For the ans. to be C

angle PSQ must be 90 degrees and PS = QS = RS

That’s what I was thinking. Thanks for the help!!
