Acute Right Scalene Obtuse
scalen since the sides are not equal and we dont know the angles to determine if it were obtuse or acute
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?
It's 7.6, right?
What is 4.2^2?
What is 6.4^2?
What is 7.6^2?
my bad i read the question wrong lol
17.6, 40.9, and 57.7
It's good haha
a=4.2^2=17.64 b=6.4^2=40.96 c=7.6^2=57.76 Add A and B.
After you find the sum of A and B, compare it to C.
Is 58.6 equal to C, which is 57.76?
Then what is it? Is is more than C or less than C?
wouldnt u use sohcahtoa
to find the angles
Side lengths, right? So you use the Pythagorean theorem. This is like the easiest lesson in Geometry.
this question has me totally confused im thinking u had to find the angles to classify it
another way would've been to use the law of sines to work out the angles.
I'm super confused
Just answer my question. :)
Is the sum of A and B greater than, less than, or equal to C?
is sine not apart of sohcahtoa
Sine, in fact, is part of the SohCahToa. S stands for Sine.
thats wat i thought so i wasnt completly wrong then
lol nope thts hilarious
No no wait
If c=sum, the triangle is right If c>sum, the triangle is obtuse If c
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.
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.
Did you get it?
So it's acute
Got it right! I'd really appreciate it if you would give me a medal. :)
Thanks for the help
