Answer 1

@lalaly can you please help me?

Answer 2

\[\tan(\theta)=\frac{opposite}{adjacent}\]in this picture u have opposite and hypotenuse .. so which trig function do u think u should use?

Answer 3

sin

Answer 4

exactly,,
so \[\sin(15)=\frac{x}{22}\]

Answer 5

i got 85.001

Answer 6

how did u get that?

Answer 7

sin(15=.258819051
22/.258819051=85.00147271

Answer 8

no thats not how u do it
\[\sin(15)=\frac{x}{22}\]now solve for x by cross multiplication\[\sin(15) \times 22=x\]\[x=5.694\]

Answer 9

oh, thank you
