Answer:

9 cm

Step-by-step explanation:

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

= 9 cm

Anyone know how to do this? 15 points.
telo118 [61]

It's angles 9 and 10.

Supplementary angles are two angles that add up to 180°.

So, supplementary angles both "stick" off of a straight line. (Because a straight line is 180°).
