Answer:
C. 75
Step-by-step explanation:
A, X=6(x-2) as his age take away 2 (his age two years ago) then multiplied by 6 will equal his current age.
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
Answer:
28x^2+3x-18
Step-by-step explanation:
Formula: (a+b)(a+b) = a^2 + a*b + a*b + b*b
Following this: 28x^2 -21x +24x -18
Then you combine like terms: 28^2 +3x-18
hope this helped!! :)
The answer to your question is: 60.3°
Data
height = 7 m
shadow = 4 m
angle = ?
Process
tangent Ф = opposite side / adjacent side
tangent Ф = 7 / 4
tan Ф = 1.75
Ф = 60.3°
