81, you just type in a calculator 3^4 which would also equal 3x3x3x3
Answer:
(1,4)
Step-by-step explanation:

(x,y)→(1,4)
The triangle has an only acute angle
X= 75
y= 105
this is because x is equal to the angle with 75, y us 105 because 180-75=105. 180 is found because the angle of a line is 180
Well 12 = 3×4 thus answer would be -3 and -4
For algebra solution, we can let smallest integer be n then that would be n(n+1) = 12, so we can go ahead and solve for n:
n(n+1) = 12
n² + n - 12 = 0
(n-3)(n+4) = 0
n = 3 or -4
Since we need negative integers, n would be -4 and then next integer (n+1) would be -3.
Hope this helps.
