Answer:
the exact value of tan(-315) is 1
The answer would be (1/8) (xy ^ 2).
Equation:
3x ^ 2 y ^ 2 / 24x
=(3/24) (x ^ 2 y ^ 2 / x)
SO simplify it is
= (1/8) (xy ^ 2)
The simplified expression for this case is given by:
(1/8) (xy ^ 2)
Hes using trigonomtery of a right angled triangle.
tan 72 = x / 12.25 where x = height of the wall
x = 12.25 * tan 72 = 37.7 feet
Well,
it says The quatient of x and seven is 5 more than three times x
The quotient = x/7
three times x = 3x
x/7 = 3x + 5 This is the answer
