Because the triangles are similar, their corresponding sides will have the same ratio. Side corresponding to PQ is AC and side corresponding to RC is PR. Thus:
RC/PR = AC/PQ
5.1 / 3.4 = 4.2 / PQ
PQ = 2.8 inches
Slope is 1/1 hope this helps
They all have to add up to 180 so add the two numbers then subtract 180 there you go got your answer
