Question 33436
So here one angle is 90 degrees .So it must be a right angled triangle
Here you are given the lengths of all the three sides
and so using trignometry you can find the values of other two angle using:
sin (angle) = {{{opposite  side/  Hypotenuse}}}
solve for the angle as you know the lengths of opposite side and hypotenuse
now solve for the angle
and when you get the angle you now have two angles and then you know how to find the third angle (180 - 90 - (angle you found out)

Hope this helps
