Answer:
345
Step-by-step explanation:
20*3 = 60 there's 60 minutes in one hour
115*3 = 345
Answer:
1/6 + 1/6 + 1/6
Step-by-step explanation:
Sum of unit fractions means to break the fraction into unit fractions
Unit fractions are the fractions with a 1 as the numerator
1/6 + 1/6 +1/6 = 3/6
same as 1+1+1 =3

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)
