Answer:
(a) 64°
(b) Yes, the ladder will be safe the ingredients will be used.
Step-by-step explanation:
(a) Trigonometric function of Sine is the appropriate formula to use to solve this question. The formula is given as:
sin θ = Opposite/Hypotenuse
θ = Angle formed with the ground = ?
Opposite = 27 ft
Hypotenuse = 30 ft
Hence,
sin θ = 27 /30
θ = arc sin (27/30)
θ = 64.158067237°
Approximately to the nearest whole number = 64°
(b) From the above calculation, the angle the ladder makes with the ground is 64° and now we want that angle to be 70°
64° is less than 70=
64° < 70°
Hence, the ladder will be safe the way it is positioned.
Answer:
3
Step-by-step explanation:
The first one is the answer.
Sketch the graph of the two by substituting x as 1, 2, 3 and you will see that the two graphs look exactly the same but seem to be reflected through the mirror line of the x-axis
Answer:
no error was made
Step-by-step explanation:
5x- 1/5*(20x +5) =9
distribute
5x - 4x-1 = 9
combine like terms
x-1 =9
add 1 to each side
x-1+1 = 9+1
simplify
x = 10
its all about the angles just subtract the number you have from the total
