Sin 0 = 12/37 find tan 0

sin α = 12/37

apply Pythagoras theorem,

Let get unknown side =y

12^2 + y^2 = 37^2

y^2 = 37^2 -12^2

y^2 = 1225

y = sqrt(1225)

y = 35

so, cos α = 35/37

Step-by-step explanation:

neither i nor ii 56 / 4.9 = 11.91489362 and 82 / (11+5) =5.125 so i is wrong

ii. (24/8+2) times 3 = 15 and (42+9)/2 =25.5

step-by-step explanation:

56

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
