Answer:

a) Only the first one is an identity.

Step-by-step explanation:

1). 8 cos O tan O csc O = 8   simplifies to:

cos O tan O csc O = 1

cos O * (sin O / cos O) * (1 /sin O)

=  cos O sin O / cos O sin O

= 1

So it is identity.

2) 13 sec^2 O/ cos^2 O - tan^2 O / cos^2O

= 13 sec^2 O - tan^2 O / cos^2 O

Now  sec^2 O = 1 + tan^2 O, so we have:

(13( 1 + tan^2 O) - tan^2 O) / cos^2 O

= (12 tan^2 O + 13) / cos^2 O

This is not always = 2 so its not an identity.

What’s the expression
aev [14]

Answer: 5 + j/3

Step-by-step explanation:

Dividing the fare equally

Since they shared the j fare evenly among 3 people, you would divide the j fare by 3 to get j/3

So each person, including Angela, paid j/3 dollars before the tip

Adding the tip

Angela then added 5 dollars to this j/3 so the expression would become 5 + j/3

Final Answer

Angela paid $5 + j/3

5+\frac{j}{3}
