Given that angle Y = 90 means that the triangle is a right angle triangle

If angle X = 30 degrees and xz =18 cm

xz is the hypotenuse side while zy is the opposite side considering the angle at X

Hence using the notation SOH CAH TOA

SOH

Sin X = zy/xz

Substituting

Sin 30 = zy/18

cross multiply

zy = 18 sin 30

zy = 18 * 0.5
