Those two angles are alternate interior angles, so they must be congruent.
3x = 2x + 20
x = 20
Answer: 34
Step-by-step explanation:
Substitute n with 9
-14+3(9-1)(2)
-14+3(8)(2)
= 34
Let the number be x, therefore, its square is x², and 44 more than the number is x+44 whose square is (x+4)².
Thus the sum will be x² + (x+44)²² = 8080
x² + x² + 88x + 1936= 8080 Combining the right terms
2x² + 8x - 6144 = 0 dividing by 2
x² + 44x - 3072 =0 solving for x
x = 37.6 or -81.6
Therefore, the positive number is 37.6
