Question

iii) Which of the following statement is true ?
a) sino = cos (90 - 0)
c) sin 0 = tan (90 - 0)
b) cos 0 = tan (90 - 0)
d) tan 0 = tan (90 - 0)

iv)cos 28°/sin 62°=?
a) 2
b) -1
c) 0
d) 1​

Answer 1

Answer:

iii) a) & iv) 1, respectively.

Step-by-step explanation:

iii) a) sin 0 = cos (90 - 0)

[tan 0 = cot (90 - 0)]

iv) cos 28 / sin 62 = cos 28 / cos (90 - 62)

= cos 28 / cos 28 = 1

Answer 2

Answer:

1. we know that sino = cos(90° - o) so the answer will be option number (a)
