The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.

where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then

Answer:
x = -12
Step-by-step explanation:
16/2
According to PEMDAS
Multiplying/dividing comes first when you read the equation from left to right
1 Simplify 1/2x^2 to x^2/2
X^2/2 - x+5=0
2 Use the Quadratic Formula
x=1+3ı,1−3ı
So the answer is the first one a
