522 divide 9= 58 58=1hour 58 x 4=232 add 232 to 522 =754
I'm assuming it is asking for surface area.
SA = 2(lw) + 2(hw) + 2(lh)
SA = 2(3*4) + 2(4*8) + 2(3*8)
SA = 2(12) + 2(32) + 2(24)
SA = 24 + 64 + 48
SA = 136 square feet
Y= x+ (x-1) ^1/3-1
y+1=x+(x-1) ^1/3
(1/3)1/3=0
y+1(1/3)= x+(x+1)
y/3=x+(x+1)
y/3=2x+1
(y/3)(2/1)=x+1
2y/3-1=x
g(x)= (2y/3-1)⁻⁻¹
Complement of an angle = 90° - x.
Supplement of the complement of an angle = 180 - (90 - x).
= 180 - 90 + x
= 90 + x
Supplement of the complement of an angle less the complement of an angle = (90 + x) - (90 - x)
= 90 + x - 90 + x
= 2x
Now, the quotient of the supplement of the angle and the number 3 is
.
It is given that supplement of the complement of an angle less the complement of an angle exceeds the quotient of the supplement of the angle and the number 3 by 73.
Therefore, 2x = 

Multiply both sides by 3.
6x = 180 - x + 219
= 399 - x
Add x to both sides.
6x + x = 399
7x = 399
Divide both sides by 7.
x = 57
Hence, the required angle = 57°.
