When given 3 triangle sides:
1) Square all 3 sides.
2) Sum the squares of the 2 shortest sides.
3) Compare this sum to the square of the 3rd side.
if sum > 3rd side² Acute Triangle
if sum = 3rd side² Right Triangle
if sum < 3rd side² Obtuse Triangle
a) 25, 36, 49
25 + 36 = 61
61 > 49

Step-by-step explanation:
x-y=2
2x+y=7
-----------
x=y+2
2(y+2)+y=7
2y+4+y=8
3y+4=8
3y=8-4
3y=4
y=4/3
x-4/3=2
x=2+4/3
x=6/3+4/3=10/3
x=10/3, y=4/3.
