Solution:

We know that:

$Area \ of \ triangle = \dfrac{1}{2} \times Base \times Height$

Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.

$Area \ of \ triangle = \dfrac{1}{2} \times 18 \times24$

Cancel out the "2" by dividing it by 18.

$Area \ of \ triangle = 9 \times24$

Simplify the multiplication.

$\bold{Area \ of \ triangle = 216 \ ft^{2}}$

Distribute
(x-3)(x+9)=-27
x^2+6x-27=-27
add 27 to both sides
x^2+6x=0
factor out x
x(x+6)=0
set each to zero
x=0
x+6=0
x=-6

x=0 and or -6

x=-6 or 0

g(7-h) +3

Now g = 5 and h=2, So lets plug the values

5(7-2) +3

= 5(5) +3

= 25 + 3

= 28

Sec θ = 3
1/cos θ = 3
cos θ = 1/3

csc (90 - θ) = 1/sin (90 - θ) = 1/cos θ = 1/(1/3) = 3

Therefore, csc (90 - θ) = 3.
