I really need help on my home work!!!
The question is " find the smallest angle of the triangle."
The lenght of the three sides are: 5.69m, 7.55m, 9.45m. and of course one of the angles is 90 degrees.
Will someone please give me the answer, if I have to ask then I do not know how to do it. and after all, this is what this place is for

The longest side is the hypotenuse, so that is 9.45 m.
A catch phrase to remember the formulas is SOH CAH TOA.
sin = opposite/adjacent
cos = adjacent/hypotenuse
tan = opposite/adjacent

Maybe you've heard of reference triangles before. If one angle is 90, you can relate it to the 1-2-square root of 3 triangle. So 5.69m is equal to the 1 in the reference triangle, 7.55m is equal to the square root of 3 in the reference triangle, and 9.45m is equal to 2 in the reference triangle. The smallest angle is opposite of the smallest side, therefore the 1-2-square root of three's smallest angle is 30 degrees. Therefore your answer is 30. I'm in precal and we're even doing trig review so I'm pretty sure that this is right.
