Sin Ф=opposite / hypotenuse
Data:
Ф=70º
opposite=12 cm
hypotenuse=x
therefore:
sin 70º=12 cm/hypotenuse
hypotenuse=12 cm / sin 70º
hypotenuse=12.770...cm≈12.8 cm
Answer: x=12.8 cm
Here, sin 70 = 12 / x
As we know, the exact value of sin 60, we can round-off, for that:
sin 60 = 12 / x
√3 / 2 = 12 / x
x = 24/√3
x = 8√3 cm
So, your final answer is 8√3 or 13.84 cm
Hope this helps!
