We will use the sine and cosine of the sum of two angles, the sine and consine of 
, and the relation of the tangent with the sine and cosine:
If you use those identities, for
, you get:
Hence:
If you use those identities, for
Hence:
Who's smart in math here can someone help me pls
1 answer:
The values of other five trigonometric ratios of the acute angle will be sin A = 3/5, tan A = 3/4, cot A = 4/3, sec A = 5/4, and csc A = 5/3.
The missing value of cos A is 4/5.
<h3>What is trigonometry?</h3>The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
Then the third side of the triangle will be
5² = P² + 4²
P = 3 units
Then the values of other five trigonometric ratios of the acute angle will be
1. sin A = 3/5
2. tan A = 3/4
3. cot A = 4/3
4. sec A = 5/4
5. csc A = 5/3
