Question

What is cos(A)? please explain

Answer 1

cos(A) = adjacent side / hypotenuse

= 4/5

Answer 2

`\small \sf \: cos ( A ) = \green{ ( 4)/( 5)} \\`

Explanation:

`\small \sf \: cos ( A ) = ( adjacent \: side )/( Hypotenuse) \\`

Where, we have given

• adjacent side is 4
• Hypotenuse is 5

substitute the values that are given

`\small \sf \: cos ( A ) = \green{ ( 4)/( 5)} \\`
