In ΔXYZ, ∠X=45° and ∠Y=61°. ∠XWZ=90° and XY=24. Find the length of XW to the nearest integer.

Answer:
15
Step-by-step explanation:
<XZY = 180-45-61 = 74°
according to sines rule :
XZ/sin Y = XY/sin Z
XZ/sin 61 = 24/sin 74
=> XZ = 24×sin 61 / sin 74
= 24× 0.87/ 0.96
= 21.75
XW/XZ = sin 45
=> XW = XZ × sin 45
= 21.75 × 0.71
= 15.44 = 15
