Question 30 Find an integral for the area enclosed by both polar graphs: r =v5sine r =v5cose 2 nt (5sine - 5 cose) de O 1 ((5 sine) - (V5 cose)?)de 01 TT / 4 2 ( ( v 5 sine ) 2 - (15 cose ) ? ) de T / 4 (( 5 sine ) 2) de 5." ( ( 5 cose ) ? ) do None of theseD Question 29 Which of the following are tangent lines to r = 2cos(90) at the pole? Select all that apply. 0 0=0 0 0 = 1/9 0 = nt/ 18 0 0 = 1/6 None of these are tangent lines at the pole
