The triangles are similar. If QR = 9, QP = 6, and TU = 19, find TS. Round to the nearest tenth.
2 answers:
9 : 19 = 6 : x
9 . x = 19 . 6
9x = 114
x = 12,6
Answer=12.6
QR=9
QP=6
TU=19
TS=?
The triangles are similar, so the following equation can be made
9 6
____=____
19 x
Cross multiply
9x=114
divide both sides by 9
x=12.6 (with the 6 repeating) or 12 2/3
TS=12.6
