Question

The answer and how to do it

Answer 1

v ≈ 4 cm

Explanation:

using the Sine rule in Δ VWX

`(v)/(sinV)` =
`(w)/(sinW)`

where v = WX and w = VX

∠ W = 180° - (126 + 21)° = 180° - 147° = 33° , then

`(v)/(sin21)` =
`(6)/(sin33)` ( cross- multiply )

v × sin33° = 6 × sin21° ( divide both sides by sin33° )

v =
`(6sin21)/(sin33)` ≈ 4 cm ( to the nearest cm )
