You multiply height x width x length to get the volume
Angles LNM and MNI are supplementary, so their measures sum to 180°. This means
∡ LNM + ∡ MNI = 180°
∡ LNM = 180° - (19<em>x</em> + 2)°
The sum of the interior angles of any triangle is also 180°, so
∡ LNM + ∡ NML + ∡ MLN = 180°
(180° - (19<em>x</em> + 2))° + (15<em>x</em> - 2)° + (6<em>x</em>)° = 180°
Solve for <em>x</em> (I'll omit the degree symbol):
180 - 19<em>x</em> - 2 + 15<em>x</em> - 2 + 6<em>x</em> = 180
2<em>x</em> - 4 = 0
2<em>x</em> = 4
<em>x</em> = 2
Then ∡ MNI = (15•2 - 12)° = (30 - 12)° = 18°.
