31-2=29 you add 2 to both sides so -2 cancels and you are left with X=31
the answer is 31
The three numbers are 52, 53, 54.
52+53=105 105+54=159
2120/100=21.2
21.2x13=275.6
Therefore there are 275.6 acres remaining of pine trees.
Answer:
Step-by-step explanation:
1). By applying Pythagoras theorem in the triangle formed by two sides and the diagonal,
Length of the diagonal = 
= 
= 25√2
AC ≈ 35.56 units
2). Since, diagonal of a square is the angle bisector of interior angles of the square,
m∠CAB = 45°
By applying sine rule in ΔABC,
sin(45°) = 


AC = 25√2
AC ≈ 35.56 units
