Question

Without using trigonometric tables, find sin 29º – cos 61°.​

Answer 1

Answer:

0

Step-by-step explanation:

sin (90-29) - cos 61

sin (90-θ) = cos θ ( complementary angle formula)

now

sin (90-29)=cos 61

=cos 61-cos 61 = 0

Answer 2

Answer:

sin (90-29) =cos 61

cos 61=cos 61

(both are cancelled)

finally the answer is 0
