Question

cos 55 = sin ?
please solve this​

Answer 1

Answer:

1 is the answer

Step-by-step explanation:

cos (55

is equal to 1

when it comes to cos and sin

it will be 1

Answer 2

answer:

1/2 +sqrt(3)/2* pi /36 is your answer without using a calculations

Step-by-step explanation:

=cos 90 cos 35+sin 90 sin 35

=0 +* sin 35

=35

=sin(30 + 5)=sin 30 cos5+cos 30 sin5=1/2*cos (5)

+sqrt(3)2/s* sin (5)

Now use approximations principle for small

angles (sin 5 and cos 5), namely, sin 5=5 and

cos 5=1

=1/2 +sqrt(3)/ 2* 5 is 5 degrees which is pi

=1/2 +sqrt(3)/2* pi /36 is your answer without using a calculations
