Question

cos28°/sin62°=? Choose the correct alternative answer for multiple choice question.
(A) 2
(B) -1
(C) 0
(D) 1

Answer 1

Given : $Given : \frac{cos 28}{sin 62}$

we know that cos(A) = sin(90 - A)

$= \ \textgreater \ \frac{sin(90 - 28)}{sin 62}$

$= \ \textgreater \ \frac{sin 62}{sin 62}$

$= \ \textgreater \ 1$


The answer is Option(D).


Hope it helps!

Answer 2

answer is = 1.

SOLUTION:-

GIVEN BY:- cos28°/sin62°
then,

using by formula sinA = cos(90-A)
we get,

$\\ \frac{cos28° }{sin62°} \\ = \frac{cos28°}{ \sin(90° -28°) } \\ = \frac{cos28°}{cos28°} \\ = 1$

YOUR RIGHT ANSWER IS OPTION (D) = 1.
