Question

Answer gets a medal (pic included)
What is tan A?



A.
4/5

B.
3/5

C.
4/3

D.
3/4

Answer 1

So Tan A = BC/AC u can find it accordingly; nt allowed to give direct solutions here

Answer 2

huh?

Answer 3

we are NOT allowed to give the direct spoonfeed answer..we can guide the step but you have to do calculations

Answer 4

how do I figure it out though?

Answer 5

well Tan of any angle is the length of opposite side divided by length of adjacent side.

so u know which is opposite and which is adjacent side?

Answer 6

is 8 adjacent and 6 opposite

Answer 7

if so then we have 8/10

Answer 8

actually that is the mistake people do.

that is for angle B.

but for angle A, the adjacent side is AC which is 6, and opposite is BC which is 8.

see from the angle A ..8 units wont look like adjacent

Answer 9

so 6/10 ?

Answer 10

well 10 is the hypotenuse we don't touch that.

the adjacent side is NEVER the hypotenuse.

so Tan A = BC/AC which is 8/6.

Answer 11

and we simplify to 4/3 correct?

Answer 12

which is answer C

Answer 13

yes

Answer 14

So for others such as cos, sin and tan NEVER touch hypotenuse

Answer 15

cos is base/hypotenuse so u consider it.

sin is opposite/hypotenuse.

but Tan = opposite/adjacent and cot = 1/Tan in these 2 cases u dnt take it

Answer 16

what would ok lets say I have



How would i do this
