Question

What is the correct ratio?

Sin 40=w/28
Tan 40=w/28
Cos 40 = w/28
Sin 40 = 28/w

Answer 1

Answer:As we know that tanФ = opposite ÷ adjacentTherefore, the correct ratio is:tanФ = opposite ÷ adjacent = w ÷ 28 = w/28i.e.tanФ = w/28Step-by-step explanation:As we know that tanФ = opposite ÷ adjacentGiven the triangle with an angle of 40°.As the opposite of an angle 40° is the length 'w', and adjacent to the angle 40° is the length '28'.As we know that tanФ = opposite ÷ adjacentTherefore, the correct ratio is:tanФ = opposite ÷ adjacent = w ÷ 28 = w/28i.e.tanФ = w/28

Answer 2

As we know that

• tanФ = opposite ÷ adjacent

Therefore, the correct ratio is:

tanФ = opposite ÷ adjacent

= w ÷ 28

= w/28

i.e.

• tanФ = w/28

Explanation:

As we know that

• tanФ = opposite ÷ adjacent

Given the triangle with an angle of 40°.

As the opposite of an angle 40° is the length 'w', and adjacent to the angle

40° is the length '28'.

As we know that

• tanФ = opposite ÷ adjacent

Therefore, the correct ratio is:

tanФ = opposite ÷ adjacent

= w ÷ 28

= w/28

i.e.

• tanФ = w/28
