Answer:
the nearest is 50%
Step-by-step explanation:
45/90 = 0.50 = 50%
Step-by-step explanation:
Given the average of 8 numbers = 56.
Then the Total sum of 8 numbers = 56 * 8
= 448.
Sum of 1st three numbers = 49 + 57 + 72
= 178.
So, the total = 448 - 178
= 270.
Average of the other 5 numbers = 270/5
= 54.
Verification:
178 + 270 = 448/8
= 56.

Answers
(sin40)/(cos40) and
(cos50)/(sin50)
Explanations
Tangent is a trigonometric ratio given by,
tan = opposite/adjacent.
lets take,
x⇒adjacent
y⇒opposite
h⇒hypotenuse
tanФ=y/x
sinФ=y/h and
cosФ=x/h
(sinФ)/(cosФ) = y/h ÷ x/h
=y/h×h/x
=y/x
This shows that
(sinФ)/(cosФ) = tanФ
We also know that,
sinФ = cos(90-Ф). So,
sin40 = cos(90-40) =cos50
So therefore;
tan40 = (sin40)/(cos40) = (cos50)/(sin50)
