Answer:
See proof below
Step-by-step explanation:
In trigonometry identity
tan^2 theta = sin^2 theta /cos^2 theta
cot^2 theta = cos^2 theta/sin^2 theta
csc^2 theta = 1/sin^2 theta
Substitute into the expression
(sin^2 theta /cos^2 theta )+ (cos^2 theta/sin^2 theta)/1/sin^2 theta
= [sin^4theta + cos^4theta/cos^2 theta sin^2 theta]÷(1/sin^2 theta)
= 1/cos^2 theta sin^2 theta÷(1/sin^2 theta)
= 1/cos^2 theta sin^2 theta * sin^2 theta/1
= 1/cos^2theta
= sec^2theta (Proved!)

Answer:Diya
Step-by-step explanation: she’s right because she is black and all black peoples is always right
The answer for this question is .18
So that each row can have the same number of chairs.
18 = 1 x 18
18 = 2 x 9
18 = 3 x 6
so we can arrange them:
1 row of 18 chairs
2 rows of 9 chairs
3 rows of 6 chairs
