The answer 1 because because 1-cosx^2 =sinx^2 and cotx^2+1=cscx^2 =1/sinx^2 and sinx^2/sinx^2=1
Hope, help and Heal.
X= entire test
if
18=.9x
then divide both sides by .9
18/ .9
and x = 20

Answer:
A: 3/5 + 2/5 = 5/5
A: 3/5 + 1/5 = 4/5
B: 3/5 - 2/5 = 1/5
B: 3/5 - 1/5 = 2/5
C: 3/5 x 2/5 = 6/25
C: 3/5 x 1/5 = 3/25
C: 2/5 x 1/5 = 2/25
D: 1/2 + 1/4 = 3/4
D: 4/5 + 4/10 = 6/5
E: 4/6 ÷ 2/6 = 2
E: 1/6 ÷ 1/6 = 1
