Answer:
Obtuse triangle.
Step-by-step explanation:
The rule to know what type of triangle it is, you do A^2 + B^2 and if it is less than C^2, then it is obtuse. If it is equal, then it is right, and if it is more than, it is acute.
Do this equation fo 7, 8, and 12
7^2 + 8^2 =? 12^2
49 + 64 =? 144
113 < 144
113 is less than 144 which means that it is an obtuse triangle
1.43 is the answer because 3.27-1.84=1.43
Answer:
The second equation can be used
Step-by-step explanation:
Just plug in the values and the equation should look like this 8^2 + b^2 = 12^2
12 is the hypotenuse to plug that into c
and 8 is just a leg so you can either put it in a or b
An=-5n+260
A40=60
So the Awnser is 60

Answer: 2 2/3
Step-by-step explanation:
we have to turn this into a improper fractions first (so its something like a bobble-head)
(2 2/5) 5 x 2 = 10 + 2 = 11/5
(3 1/4) 3 x 4 = 12 + 1 = 13/4
Then add those two.
11/5 + 13/4
11 + 13 = 24
5 + 4 = 9
so now its time to put it in simplest form 8/3
Now 8 divided by 3...BUT WAIT...3 can't go into 8
Now we turn it into a Mixed Number 2 2/3
