I am attempting to solve a basic trigonometry problem. I just don't understand how to find the sides of a right triangle when only the angles are given. The angles are of course on 90-degree angle (it is a right triangle), a 67-degree triangle, and a 23-degree angle. Thanks for any help you can provide for me about finding the sides of a right triangle when only given the angles. wink

You will not be able to find the sides given just the angles. The reason for this is that there are many similar right triangles with the same given angles......but........all of them will have differing sides......so.....we need to know the length of at least one side of this triangle in order to find the others

Thank you! I realized that you are allowed to record the answer as "can not be determined". I guess that fits its description. Thanks again!!! wink

If you only have three angles then you know the shape the triangle will take but you will not know the exact length of a side.

You could have a triangle with all those angles and sides of 34, 23,78 and you could also have another triangle with the same angles and sides of 68,46,156.

That is very true. Thank you. I think that my teacher would want exact answers if anything, although, but thank you for the help anyway!  smiley
