sine x = opp / hypotenuse
sine x = 4 / 9 = .44444444444444444
angle x = arc sine (.44444444444444444)
Using the handy calculator here:
http://www.1728.org/trigcalc.htm
the arc sine of (.444444444444) =
26.388 Degrees

ohh thank you

You need the second one done and the diagram is wrong.

please do the secound one
OpenStudy (wolf1728):
Cosine x = adj / hyp = 10/14 = 0.7142857143
Arc Sine 0.7142857143 = 45.585 Degrees
I'll have to check that with the other calculator
OpenStudy (wolf1728):
It says the angle is
45.585degrees
It's handy to have the calculators to check the work. :-)

You'll have to recheck that second problem to make sure I redrew the diagram correctly.
