C. What percent of the students sold 20 or more tickets?

PLEASE HURRY ​

Q. 10.tan theta +cot theta = sec theta csc theta

Ans.

start from left side

tan theta + cot theta

convert sines into cosines

write tan theta in sines and cosines using quotient identity

sin theta/cos theta/cot theta

write cot theta in sines and cosines using quotient identity

sin theta/cos theta+cos theta/sin theta

sin theta sin theta+cos theta cos theta/cos theta sin theta

Apply pythagorean identity

1/cos theta csc theta

1/cos theta.1/sin theta

Multiply 1/cos theta and 1/sin theta

1/cos theta sin theta
