Step-by-step explanation:
Using the cosine and tangent trigonometric ratios and the exact values
cos30° = and tan30° =
, then
cos30° = =
=
( cross- multiply )
× m = 12 ( divide both sides by
)
m = ← rationalise by multiplying numerator/ denominator by
)
m = ×
=
= 4

tan30° = =
=
( cross- multiply )
× n = 6 ( divide both sides by
)
n = ← rationalise the denominator
n = ×
=
= 2
