Question

what is the value of cos55+sin55​

Answer 1

Answer:

mrk brainliest nd thnks me tooooo plssss dearr

Step-by-step explanation:

(sin55-cos55)/sin10

sin(90-35)-cos55/sin10

cos35-cos55/sin10

[-2sin(35+55/2).sin(35-55/2)]/sin10

[+2sin45.sin10]/sin10

/sqrt{2}

Answer 2

Answer:

$= cos55 + sin55 \\ = cos(90 - 35) + sin55 \\ = sin35 + sin55 \\ = sin90 \\ = 1$

hope this helps....

pls mark as brainliest....
