Question

Hi could someone please show me how to calculate the length of TR on the picture below

Answer 1

Use the similarity of triangles concept.

∆WMT is similar to ∆WQR

Get all the similarity ratios.

PQ = RS = 12

WT/TR = WS/RS = 1/3

TR = 3WT........[|]

3x + X = 16

X = 4

TR = 12 cm.

The question is hypothetically incorrect.
