Acute Right Scalene Obtuse
anonymous
  • anonymous
scalen since the sides are not equal and we dont know the angles to determine if it were obtuse or acute
anonymous
  • anonymous
Let "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.

So what is the longest side?
anonymous
  • anonymous
It's 7.6, right?
anonymous
  • anonymous
Yeah
anonymous
  • anonymous
What is 4.2^2?
anonymous
  • anonymous
What is 6.4^2?
anonymous
  • anonymous
What is 7.6^2?
anonymous
  • anonymous
my bad i read the question wrong lol
anonymous
  • anonymous
17.6, 40.9, and 57.7
anonymous
  • anonymous
It's good haha
anonymous
  • anonymous
a=4.2^2=17.64 b=6.4^2=40.96 c=7.6^2=57.76 Add A and B.
anonymous
  • anonymous
After you find the sum of A and B, compare it to C.
anonymous
  • anonymous
58.6
anonymous
  • anonymous
Is 58.6 equal to C, which is 57.76?
anonymous
  • anonymous
No
anonymous
  • anonymous
Then what is it? Is is more than C or less than C?
anonymous
  • anonymous
wouldnt u use sohcahtoa
anonymous
  • anonymous
to find the angles
anonymous
  • anonymous
Just what you said @joquez14 , you only use sohcahtoa to find the angles. Look up the question again. What is the given?
anonymous
  • anonymous
Side lengths, right? So you use the Pythagorean theorem. This is like the easiest lesson in Geometry.
anonymous
  • anonymous
this question has me totally confused im thinking u had to find the angles to classify it
Sepeario
  • Sepeario
another way would've been to use the law of sines to work out the angles.
anonymous
  • anonymous
@NICK702222 you still there?
anonymous
  • anonymous
Yeah
Sepeario
  • Sepeario
so @joquez14 if you want to evaluate the angles you can also do that.
anonymous
  • anonymous
I'm super confused
anonymous
  • anonymous
Just answer my question. :)
anonymous
  • anonymous
Is the sum of A and B greater than, less than, or equal to C?
anonymous
  • anonymous
is sine not apart of sohcahtoa
anonymous
  • anonymous
@Sepeario Just trying to help her find the easiest solution. :)
anonymous
  • anonymous
Sine, in fact, is part of the SohCahToa. S stands for Sine.
anonymous
  • anonymous
thats wat i thought so i wasnt completly wrong then
anonymous
  • anonymous
Is 58.6 equal to 57.7? Is 58.6 more than 57.7? Is 58.6 less than 57.7? @NICK702222
anonymous
  • anonymous
Nope
anonymous
  • anonymous
Obtuse?
anonymous
  • anonymous
lol nope thts hilarious
anonymous
  • anonymous
No no wait
anonymous
  • anonymous
If c=sum, the triangle is right If c>sum, the triangle is obtuse If c
anonymous
  • anonymous
You're almost there. :)

First 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.
anonymous
  • anonymous
If 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.
anonymous
  • anonymous
Did you get it?
anonymous
  • anonymous
So it's acute
anonymous
  • anonymous
Got it right! I'd really appreciate it if you would give me a medal. :)
anonymous
  • anonymous
Thanks for the help
