Answer:

see 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

6²+4²=h²
36+16=h²
