Answer 2

Solving for cosa, tga, and cta

To solve for cosa, tga, and cta when Sina is equal to 5/13, we can use trigonometric identities and relationships.

First, let's find cosa: The formula for cosa is cosa = √(1 - sin^2a), where a is the angle and sin^2a is the square of the sine of the angle.

Given that Sina = 5/13, we can calculate cosa using the formula: cosa = √(1 - (5/13)^2)

Next, let's find tga: The formula for tga is tga = sin a / cosa, where a is the angle, sin a is the sine of the angle, and cosa is the cosine of the angle.

Given that Sina = 5/13 and we have already calculated cosa, we can calculate tga using the formula: tga = (5/13) / cosa

Finally, let's find cta: The formula for cta is cta = 1 / tga, where tga is the tangent of the angle.

Given that we have already calculated tga, we can calculate cta using the formula: cta = 1 / tga

Let's calculate these values.
