Di Bawah ini di berikan tiga segitiga siku siku, Diketahui Sin Ф = 2/5 tentukanlah nilai X
Syubbanasin = sisi depan / sisi miring a) sin x = 2/5 6/x = 2/5 2x = 30 x = 15 b) sin x = 2/5 x/8 = 2/5 5x = 16 x = 16/5 c) sin x = 2/5 tan x = 2/(V(5^2-2^2) = 2/V21 tan x = 2/V21 x/12 = 2/V21 x = 24/V21 x = 24/21 V21 = 8/7 V21
a) sin x = 2/5
6/x = 2/5
2x = 30
x = 15
b) sin x = 2/5
x/8 = 2/5
5x = 16
x = 16/5
c) sin x = 2/5
tan x = 2/(V(5^2-2^2) = 2/V21
tan x = 2/V21
x/12 = 2/V21
x = 24/V21
x = 24/21 V21
= 8/7 V21
