; where a = 1, b = -4 and c = 8
The answer is A because the diagram shows
13 is a prime number because you can't multiply 2 numbers to make 13
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
26 multiplied by .40= 10.4
