Answer:
option D is true.
Step-by-step explanation:
The right-angled triangle is shown.
From the right-angled triangle,
The angle Ф = 60°
We know that the trigonometric ratio
tan Ф = opposite / adjacent
Thus,
tan 60 = 4 / n
√3 = 4/n
n = 4/√3
Thus,
n = 4/√3
= (4 × √3) / (√3 × √3)
= 4√3 / 3
Thus,
n = 4√3 / 3
Using Pythagorean theorem
m = √n²+4²
Thus,
Therefore, option D is true.
Answer:
Solving the equation 
for variable n we get 
Step-by-step explanation:
We need to solve the equation for variable n
Solving:
Subtract both sides by 6p
Switch sides of equality
Divide both sides by 3
So, solving the equation for variable n we get
Answer: 24:34
Step-by-step explanation:
If you multiply the ratio by 2, for example, it will still be equal.
100 percent because 45 % is always in between 30 and 50 %
Answer:
Step-by-step explanation:
15% = 15/100= 0.15
45% = 45/100 = o.45
Remaining students: 40% = 40/100 = 0.4%
