Question

if tan A = x/y, then

cos A + sin A/cos A - sin A​

Answer 1

Answer:

hey here is your answer

pls mark it as brainliest

so here we go

Step-by-step explanation:

now we know that tan A=sin A/cos A

thus sinA/cos A=x/y

so by applying componendo-dividendo property

we get

sinA+cosA/cosA-sinA=y+x/y-x

thus your final final answer is y+x/y-x
