Two triangles

[joannamartinez]

I really need help please. I have two triangles that are connected at one point. I need to find first if the two triangles are similiar. Then I need to find the indicated side of PQ and round the answer to the nearest hundredth. One triangle is PQR and the other is RST. PQ = ?, QR = 92, RS = 78, ST = 98. I do not understand these. PQR triangle seems slightly larger to me. Please advise. Thank you.

Do you know how to prove that two triangles are similar & Do you know how to set up the ratio of similarity . . .

No. I am not good at these problems. Please advise. Thank you.

Without seeing the diagram, it's hard to decide whether or not the triangles are similar.

Are the triangles aligned such that PRT is a straight line?

Is there any other information shown on the diagram that you have not posted? In particular, I'm wondering if there's any given indication that angle QRP equals angle SRT.

PRT is a straight line. QRS is a straight line. Does that help?
