Answer 1

cos(A) = adjacent/hypotenuse

which side is the side adjacent to A?
which is the hypotenuse?

Answer 2

A= 10?

@Vocaloid

Answer 3

uh, not quite

which side is adjacent to A?

Answer 4

26

Answer 5

that's the hypotenuse, try again

Answer 6

@Vocaloid 24?

Answer 7

nope, try again...

adjacent means the side next to the angle, NOT including the hypotenuse

Answer 8

i dont understand

Answer 9

see how "opposite" is on the opposite side of the triangle?
see how "adjacent" is next to A but NOT the hypotenuse?
see how the hypotenuse is the longest side?

so, if cos(A) = adjacent/hypotenus, what is cos(A)?

Answer 10

yes

Answer 11

so, what is cos(A)?

Answer 12

24

Answer 13

no, keep trying...

cos(A) = adjacent/hypotenuse

what is the adjacent side?

Answer 14

10

Answer 15

great! what's the hypotenuse?

Answer 16

26

Answer 17

great! so, if cos(A) = adjacent/hypotenuse, what is cos(A)?

Answer 18

10/26

Answer 19

awesome! you're done ~

Answer 20

can you help me with more?

Answer 21

sure

Answer 22

AB is opposite to C and AC is adjacent to C, right?

we know that tan(C) = opposite/adjacent, so tan(C) = 4/9
solve for C
