<u>Given:</u>
It is given that the ridge is 360 inches tall.
<u>Assumptions:</u>
Assume you are 170.1 cm tall which equals 67 inches tall, the height from your eye to the floor is
inches.
The distance from your eye level to the bottom of the ridge is 427 inches.
Assume the angle A is 60°.
<u>To find the distance from you to your dog.</u>
<u>Solution:</u>
A right-angled triangle can be formed where the angle is 60°, the distance between you and the dog is the hypotenuse of the triangle and your height from the floor is the adjacent side of the triangle.
Assume the hypotenuse of the triangle measures x inches.
To determine the length of the hypotenuse, we determine the cos of the angle.



So if the ridge is 360 inches tall and you are 67 inches tall and the angle A is 60°, the distance between your dog and you is 854 inches.
Answer:
110
Step-by-step explanation:
Using the expansion
(a + b)³ = a³ + b³ + 3ab(a + b)
Given
x +
= 5 ( cube both sides )
(x +
)³ = 5³ = 125 ← expand left side using identity
x³ +
+ 3(x ×
)(x +
) = 125
x³ +
+ 3(1)(5) = 125
x³ +
+ 15 = 125 ( subtract 15 from both sides )
x³ +
= 110
The important information's already given in the question can be used to find the correct answer.
In 1 hour Ursula earns = 9 dollars
So
In h hours Ursula earns = (9/1) * h dollars
= 9 * h hours
= 9h hours
So we have found from the above discussion that Sarah wrote the correct answer and it was 9h.
