Answer:
Cos(90°-24°)= Sin 24° = 0.4067
Step-by-step explanation:
In the question i consider (90-24) as degree(°)
As we know, 90°-A lies in 1st quadrant and every trigonometric function is +ve in 1st quadrant. The trigonometric function changes when angle is either 90° or 270°, and remains unchanged when angle is either 180° or 360°.
So, according to that,
Cos(90°-A)= Sin A
So, here,
Cos(90°-24°)= Sin 24°
And using scientific calculator we can find the value of Sin 24° = 0.4067
