Question

Find the missing length. The triangles in each pair are similar.

Answer 1

1) 117

2) 24

Explanation:

Corresponding sides are in the same ratio for similar triangles

1)

For triangles MUL and WUV:

UW/UM = UV/UL

?/45 = 104/40

? = 45 x 104/40 = 117

2)
For triangles RST and RKH
RS/RK = RT/RJ

?/12 = 20/10 = 2

? = 2 x 12 = 24
