I can help

OpenStudy (anonymous):
Okay! thanks! I attached it
OpenStudy (okdutchman7):
Since the triangles are similar their measures would be the same
OpenStudy (okdutchman7):
So the answer is 40 degrees

This is wrong
OpenStudy (anonymous):
So since the <QPR is bigger would this be 80 degrees?
OpenStudy (okdutchman7):
No because the two triangles are similar which means that the corresponding angles are the same
OpenStudy (lightn1ng):
It states measure of angle QPR, P being the point where the angle is
OpenStudy (okdutchman7):
according to the proof that corresponding parts of congruent triangles are congruent (cpctc)

Yeah plus only two of the triangles are the same I know its not 140, so it has to be either 80, or 20 then
OpenStudy (okdutchman7):
The answer is 40.
OpenStudy (okdutchman7):
not 80 or 20
OpenStudy (lightn1ng):
my fault okdutchman, i read the question wrong
OpenStudy (lightn1ng):
He right
its 40
because the congruency markers tell you

OpenStudy (lightn1ng):
Yes
OpenStudy (okdutchman7):
Absolutely I got a 99 in Geometry.
OpenStudy (anonymous):
Okay thank you very much! I have another question so keep an eye open!
