Question

If sin 35° =cos x° write down the value of x

Answer 1

Answer:

65

Step-by-step explanation:

sin35=cos(90-35)

sin35=cos65

Answer 2

Answer:

$sin \: 35 \degree \: = cos \: x \\ \implies \: sin \: 35 \degree = sin(90 \degree - \: x )\\.. \{\because sin(90 \degree - \theta) = cos \theta\} \\ \implies 35 \degree = 90 \degree - \: x \\ \implies \: x = 90 \degree - 35 \degree \\ \implies \: \huge \fbox{x = 55 \degree}$
