Question 1064457: In ΔXYZ, measure of angle∠Y equals=78, XY equals=99, and XZ equals=13. To the nearest tenth, what is measure of angle∠Z? This is apart of the law sines. Thanks. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! This has to be drawn. I am assuming that XY= 9.9, otherwise this can't be solved.
y/sin Y=z/sin Z
13/sin 78=99/sin Z
13.29=9.9/sin Z
sin Z=9.9/13.29
=0.7449.
take the arc sin of that, and Z=48.15 degrees.
