(a) Given that sin y = \(\frac{8}{17}\) find the value of \(\frac{tan y}{1 + 2 tan y}\) (b) An amount of N300,000.00 was shared among Otobo, Ada and Adeola....

Answer Details

(a) Finding tan(y) using sin(y):

We cannot directly find the tangent (tan) of an angle using only the sine (sin). However, we can use the trigonometric identity:

tan^2(x) + 1 = sec^2(x)

where x is the angle and sec(x) is the secant (1/cos(x)).

Here's how to solve for tan(y):

1. We are given sin(y) = 8/17. We cannot find cos(y) directly from this information.
2. Since we cannot isolate tan(y) from the given identity, we cannot directly calculate its value.

Therefore, it's impossible to determine the value of

tan(y) + 2tan(y)/(1 + 2tan(y)) with the given information.

(b) Sharing Money:

Step 1: Calculate the remaining amount after Otobo's share.

Total money - Otobo's share

= N300,000.00 - N60,000.00 = N240,000.00

Step 2: Find Ada's share.

Ada receives 5/10 (which is the same as 1/2) of the remaining amount.

Ada's share = N240,000.00 * (1/2) = N120,000.00

Step 3: Calculate Adeola's share.

The remaining amount goes to Adeola.

Adeola's share = Total remaining - Ada's share

= N240,000.00 - N120,000.00 = N120,000.00

Step 4: Determine the ratio of shares.

Otobo : Ada : Adeola

= N60,000.00 : N120,000.00 : N120,000.00

Ratio: 3 : 6 : 6 (simplifying, 1 : 2 : 2)

Therefore, the money was shared in a ratio of 1 : 2 : 2 among Otobo, Ada, and Adeola respectively.
