Answer: B 45º
Step-by-step explanation:
If the sine and cosine are the same, the angles would need to be the same. In an isosceles triangle, the angles are the same and therefore the sine and cosine would also be the same.
For [tex]45^{0}[/tex] acute angle, the sine of the angle and cosine of the angle equal.
What is an acute angle?
"An acute angle that measures less than 90 degrees. It is between [tex]0^{0}[/tex] and [tex]90^{0}[/tex]. "
According to the question
The sine of the angle and cosine of the angle are equal
sinθ = cosθ
⇒ sinθ/cosθ = 1
⇒ tanθ = 1
⇒ tanθ = tan [tex]45^{0}[/tex]
⇒ θ = [tex]45^{0}[/tex]
Hence, For [tex]45^{0}[/tex] acute angle, the sine of the angle and cosine of the angle equal.
