Question 1012070
.
Consider a triangle with side lengths of 10 ft, 17.32 ft, and 20 ft. 
By examining the side lengths, what can you conclude about the measurement of the angles? Explain your reasoning
----------------------------------------------------------------


{{{sqrt(3)}}} = 1.732 (approximately).


Correspondingly, {{{10*sqrt(3)}}} = 17.32.


Also note that {{{sqrt(20^2-10^2)}}} = {{{sqrt(300)}}} = 17.32 (approx.)


So it looks like this triangle is right-angled triangle with one acute angle of 60 degree and the other acute angle of 30 degree.
