In triangle ABC, triangle C is a right angle. Find the remaining sides and angles. Round your answer to the nearest tenth. a=3, c=19

Question

raden · Answer

i assumed that the remaining sides is b, so use the pythagorean theorem :
b^2 = c^2 - a^2
b^2 = 19^2 - 3^2
b^2 = (19+3)(19-3)
b^2 = 22 * 16
b = sqrt(22 * 16) = sqrt(19) * sqrt(16) = ....

a.ma=9.1degrees, mb=80.9 degrees, b=18.8                                                     b.ma=80.9 degrees, mb=9.1 degrees, b=18.8                                                    c. ma=14.5 degrees, mb=75.5 degrees, b=18.8                                                     d. ma=75.5 degrees, mb=14.5 degrees, b=18.8

raden · Answer

sqrt(19) = ... (use ur calculator)
sqrt(16) = 4
multiply of them

raden · Answer

woops... 
sorry, i mean sqrt(22) * sqrt(16) = ...

anonymous · Answer

i got 18.761 is that right?

raden · Answer

yes, take nearst be 18.8

raden · Answer

now, to find the measure of angles A and be, u need trigonometry ...

raden · Answer

* A and B i mean :)
