It's a bit of a bummer to have to work through all of these to find the answer. That a lot of slope calculations (or graphing, or whatever). When there are this many, a spreadsheet or other machine help can make it easier.
The correct choice is the last one, XYZ, with vertex X being where the right angle is located.
_____
Slope of XY is 4/7; slope of XZ is -7/4. The product of these is -1, so those segments are at right angles.
#1 is a right isosceles
#2 I think is equilateral
#3 it is obtuse
#4 I think its scalene
I hope I helped :)
Answer:
20 gallons
Step-by-step explanation:
If 4 big water bottles can hold 8 gallons then just multiply 10x2 because that is double the amount.
Answer:5
Step-by-step explanation:
3^2+4^2=c^2
9+16=c^2
25=c^2
=c
5=c
Pythagorean theorem a^2+b^2=c^2
