Answer:
x = 3, y = 2
Step-by-step explanation:
Substitute the values of x from each alternative in the previous <em>question</em>, then solve for y. This is depicted below.
- <em>A. y = -7, x = 5, 4(5) + 2y + 3 = 19</em>
- <em>B. y = 0 and x = 4, 4(4) + 2y + 3 = 19</em>
- <em>C. y = 2 and x = 3, 4(3) + 2y + 3 = 1</em>
- <em>D. y = 4, x = 2, 4(2) + 2y + 3 = 19</em>
Only the third option has a y value that is <em>comparable</em> to the value in the computations, according to the calculations.
As a result, the letter C is the correct response.
Answer: The top of the Crane is 31 feet above the ground.
Step-by-step explanation:
When it is fully extended, the crane arm forms a 30 degree angle with a line parallel to the ground. This means that a right angle triangle is formed. The length of the Crane's arm represents the hypotenuse. The horizontal distance represents the adjacent side of the right angle triangle. The distance, h of the top of the Crane from the ground represents the opposite side of the right angle triangle.
To determine h, we would apply
the Sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 30 = h/62
h = 62Sin30
h = 62 × 0.5
h = 31 feet
