Question

1. Without using trigonometric table, find the values
of the following:
(i) cos277° - sin213°
(ii)sin54°/cos36°+cos54°/sin36°​

Answer 1

Answer:

1. xx. 2.

Step-by-step explanation:

I. cos 83 + Sin 33 = sin 7 + sin 33 can't resolve without tables.

ii. cos 36 = sin 54 , cos 54 = sin 36

hence 1/1 + 1/1 = 2
