Answer:
Step-by-step explanation:
Don't use 0 as a substitute for θ. 0 is always 0.
cosθ = -5/(2√15)
secθ = 1/cosθ = -2√15/5
Step-by-step explanation:
2/5+2/4 (find common denominator)
The common denominator is 20
2/5 is 8/20 (multiply by 4)
2/4 is 10/20 (multiply by 5)
8/20+10/20 is 18/20
If you simplify 18/20 this would by 9/10 if you divide by 2
so the total is 18/20 or 9/10 simplified
Hope this helps!!!!
Have a nice day :)
