Question

Sinx=cos19∘sinx=cos19∘ what is the value of x? enter your answer in the box. x = °

Answer 1

x=90
sin90=1
cos19 x 1=cos19

Answer 2

Answer:

The value of x is 71°.

Step-by-step explanation:

The given equation is

$\sin x=\cos 19^{\circ}$

According to the property of trigonometry,

$\cos\theta^{\circ}=\sin (90-\theta)^{\circ}$

Using the property of trigonometry,

$\sin x=\sin (90-19)^{\circ}$

$\sin x=\sin (71)^{\circ}$

On equating both the sides we get

$x=71^{\circ}$

Therefore the value of x is 71°.
