I need help with this question for geometry!

OpenStudy (okdutchman7):

I can help

OpenStudy (anonymous):

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

OpenStudy (lightn1ng):

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)

OpenStudy (anonymous):

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 (anonymous):

Are you for sure that's the answer like totally certain!

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!

OpenStudy (lightn1ng):

Sure man
