Question

if 1+sinA/cosA +cosA/1+sinA =4 then find A value​

Answer 1

Answer:

60°

Step-by-step explanation:

((1+ sinA)/cosA + cosA/(1+sinA) = 4

[(1+sinA)^2 + cos^2A]/cosA(1+sinA)=4

(1+sin^2A+2sinA+cos^2A)/cosA(1+sinA)

= 4

2 + 2sinA/cosA(1+sinA) = 4

2(1 + sinA)/cosA(1+sinA) = 4

2 = 4 cosA

cosA = 2/4 = 1/2

cosA = cos 60° => A = 60°
