Best ResponseYou've already chosen the best response.0scalen since the sides are not equal and we dont know the angles to determine if it were obtuse or acute

Best ResponseYou've already chosen the best response.0Let "c" be the longest side on each set of three numbers. If c^2 = a^2+b^2, the triangle is right If c^2 > a^2 + b^2, the triangle is obtuse If c^2 < a^2 + b^2, the triangle is acute.

Best ResponseYou've already chosen the best response.0a=4.2^2=17.64 b=6.4^2=40.96 c=7.6^2=57.76 Add A and B.

Best ResponseYou've already chosen the best response.0Is 58.6 equal to C, which is 57.76?

Best ResponseYou've already chosen the best response.0Just what you said @joquez14 , you only use sohcahtoa to find the angles. Look up the question again. What is the given?

Best ResponseYou've already chosen the best response.0Side lengths, right? So you use the Pythagorean theorem. This is like the easiest lesson in Geometry.

Best ResponseYou've already chosen the best response.0this question has me totally confused im thinking u had to find the angles to classify it

Best ResponseYou've already chosen the best response.0another way would've been to use the law of sines to work out the angles.

Best ResponseYou've already chosen the best response.0so @joquez14 if you want to evaluate the angles you can also do that.

Best ResponseYou've already chosen the best response.0Sine, in fact, is part of the SohCahToa. S stands for Sine.

Best ResponseYou've already chosen the best response.0Is 58.6 equal to 57.7? Is 58.6 more than 57.7? Is 58.6 less than 57.7? @NICK702222

Best ResponseYou've already chosen the best response.0If c=sum, the triangle is right If c>sum, the triangle is obtuse If c<sum, the triangle is acute.

Best ResponseYou've already chosen the best response.0First use the distance formula to find the sides. After using the distance formula, you can use Cosine Law to find the angles. But for this problem, one just needs to use the distance formula to find the sides and then graph it and they they tell what type of triangle and to check if it is a 90 or not they can use \( a^2+b^2=^c \) but one can also use this to tell for the other too, but you might be able just to eye it to tell.

Best ResponseYou've already chosen the best response.0If 57.7=58.6, the triangle is right If 57.7>58.6, the triangle is obtuse If 57.7<58.6, the triangle is acute.
