Question 1146878
.
In a right triangle, the length of one of the legs is 8 cm and the measure of the acute angle opposite to this leg is 50°. 
Find the measure of the other acute angle and the lengths of the other leg and the hypotenuse.
~~~~~~~~~~~~~~~~~~



<pre>
The other acute angle is  90° - 50° = 40°.


The other leg is 8*tan(40°).


The hypotenuse is  {{{8/cos(40^o)}}}.

When I see the solutions of some tutors at this forum that use INADEQUATELY complicated tools for simple tasks, 
I often doubt if they know the Math, at all.


When you work with right triangles, the "law of sine theorem" is irrelevant ---- the trigonometric functions perform all needed operations . . .
