Answer:
x° ≈ 50.0°
Step-by-step explanation:
The sides adjacent and opposite the angle are given. The appropriate trig relation is ...
Tan = Opposite/Adjacent
tan(x°) = 50/42
The inverse function is used to find the angle whose tangent is a particular value:
x° = arctan(50/42) ≈ 49.9697°
x° ≈ 50.0°

Let the one's digit be y and tens digit be x,
Number = 10x + y
Then,x=3y⋯(i)
Reversed number = 10y + x
A.t.Q :- (10x+y)−(10y+x)=36 Put x = 3y in eq. (i)
⇒9x−9y=36
⇒x−y=4⋯(ii)
⇒3y−y=4
∴2y=4 x=3y ∴x=6
y=2
∴ Number = 62
Answer: 4.2
Step-by-step explanation:
Answer:
27.968 minutes
Step-by-step explanation:
let x be the original time it takes to make the piece. Given production time was cut down in two phases by 8% and 5%, the new time of the piece is calculated as:
We therefore substitute the initial time in the equation:
Hence, it now takes 27.968 minutes to manufacture the piece.
