<span><u><em>Answer:</em></u>
d = 25
<u><em>Explanation:</em></u>
To get the value of d, we will need to isolate the d on one side of the equation.
<u>This can be done as follows:</u>
</span>
<span>
<u>First, we will do cross multiplication as follows:</u>
40*15 = 24*d
600 = 24d
<u>Then, we will isolate the d as follows:</u>
24d = 600
</span>
<span>
d = 25
Hope this helps :)</span>

Answer:
see explanation
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
