Answer:
Part 1) ![x=15\°](https://tex.z-dn.net/?f=x%3D15%5C%C2%B0)
Part 2) ![cos(75\°)=0.2588](https://tex.z-dn.net/?f=cos%2875%5C%C2%B0%29%3D0.2588)
Step-by-step explanation:
Part 1) we have
![sin(x)=0.2588](https://tex.z-dn.net/?f=sin%28x%29%3D0.2588)
using a calculator
![x=sin^{-1}(0.2588)=15\°](https://tex.z-dn.net/?f=x%3Dsin%5E%7B-1%7D%280.2588%29%3D15%5C%C2%B0)
Part 2)
we know that
If two angles are complementary
------> complementary angles
then
![cos(\alpha)=sin(\beta)](https://tex.z-dn.net/?f=cos%28%5Calpha%29%3Dsin%28%5Cbeta%29)
In this problem
we have
![x=15\°](https://tex.z-dn.net/?f=x%3D15%5C%C2%B0)
The angle complementary to x is equal to
![90\°-15\°=75\°](https://tex.z-dn.net/?f=90%5C%C2%B0-15%5C%C2%B0%3D75%5C%C2%B0)
so
![cos(75\°)=sin(15\°)](https://tex.z-dn.net/?f=cos%2875%5C%C2%B0%29%3Dsin%2815%5C%C2%B0%29)
therefore
![cos(75\°)=0.2588](https://tex.z-dn.net/?f=cos%2875%5C%C2%B0%29%3D0.2588)
