Answer:
0.9231
Step-by-step explanation:
To get the exact value of cos(arcsin(5/13)),
First we need to get the value of the trigonometry function in the bracket i.e arcsin5/13.
arcsin 5/13
= arcsin 0.3846
= 22.62°
Then we will take the cos of the resulting value to give the final exact value of the trigonometry function.
= cos (22.62°)
= 0.9231
The exact value of the given trigonometry function is 0.9231
