Idon’t understand when it says first across the y-axis and then across the x-axis.?

The sketch shows two parallel lines cut by a transversal. angle 2 2 is 36° 36 ° . what is the measure of angle 8 8 ?

With this question substitute t=3 and t=5 to determine if the two expressions are equivalent. 4(t + 3) 4t+12 which statements are true? check all that apply. a. the value of both expressions when t =5 is 32. b. the two expressions are not equivalent. c. the value of both expressions when t=3 is 15. d. the value of both expressions when t=5 is 23. e. the two expressions are equivalent. f. the value of both expressions when t=3 is 24.

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
