Hope it helps <3 :)
The answer would be around 4.5 or 4.6
x = 4.5 so it is 3/-8 = 4.5/12
Answer:
5/13
Step-by-step explanation:
sine=opposite/hypotenuse
cosine=adjacent/hypotenuse
opposite=-12 (I know that this is not possible)
hypotenuse=13
These are ratios, not real lengths
using the Pythagorean theorem, the other leg is 5
cos (theta)=5/13
