Rule of trigonometric functions:-
sin a = cos(90 - a)
Here a = 90°.
sin 90 = cos (90 - 90)
1 = cos 0.
cos 0 = 1.
So the cos 0 = 1.

X+(x+1)=y. The first integer would be x, and the second would be one more than x, so x+1. I'm not sure if there's a specific number they are supposed to total, so I just set it equal to y. If there is a specific number, just replace y with that number. Hope this helps!
Answer:
-1 <x < 7
(-1,7)
Step-by-step explanation:
open circle on the left means the number is greater than
-1 <x
Open circle on the right means the number is less than
x < 7
Since both statements are true. we combine them
-1 <x < 7
open circles means parentheses, closed circles mean brackets
