Question

Look at the figure.

Answer 1

?

Answer 2

Based on the figure, which equation is true? (4 points)
Select one:
a. cos x° = tan y°
b. tan x° = sin y°
c. sin x° = cos y°
d. sin x° = tan y°

Answer 3

i think its B but im not sure

Answer 4

Answer 5

@Nurali

Answer 6

"..i think its B.."
Can you show me your working ??

Answer 7

considering the triangle ABC u can write an expression for sin (x)

considering the triangle ADC u can write an expression for cos (y)..

since the values u need r given in the diagram... u can find the exact values of sin (x) and cos (y)...

then compare them... u will have ur answer ..:)

Answer 8

I just wanted someone to ttell me if im correct or not

Answer 9

... u r incorrect with ur answer... it's not b

Answer 10

and while you guys are on here can someone answer this one real fast

Answer 11

If the cos 30° is 0.866, then the sin __________ is 0.866.

Answer 12

that's y i gave u the hint to find it....

Answer 13

Also giving answers is against the CoC..

Answer 14

\[\cos \theta = \sin ( 90 - \theta)\]

Answer 15

i know iknow i just needed it so i wont get grounded please guys

Answer 16

use this to find the answer for the second question :)

Answer 17

ok its 60 for the d one correct

Answer 18

yesh! it's 60

Answer 19

and for the first one?

Answer 20

but u didnt try ur first question...
in triangle ABC
\[\sin( x) = \frac{ opposite \ side }{ hypotenuse } = \frac{ BC }{ AC } = ?\]

Answer 21

in triangle ADC
\[\cos (y) = \frac{ adjacent \ side }{ hypotenuse } = \frac{ AC }{ DC } = ?\]

Answer 22

will there be "cos" in the answer

Answer 23

find the 2 values that u will get for sin(x) and cos(y).. it will give u , ur answer

Answer 24

yes... cos will be in the answer :)

Answer 25

so you are saying the answer is C

Answer 26

huh ?

Answer 27

OH! i c... there is only one choice with "cos"

Answer 28

ok so it is C

Answer 29

i didn't mean to give u the answer directly... but yes , it's C

Answer 30

thank you !!
