Sagot :
Step-by-step explanation:
We know that,
[tex]\boxed{\sf \sin θ = \dfrac{Opposite \: side}{Hypotenuse}}[/tex]
[tex]\longmapsto \sf \sin 30^{\circ} = \dfrac{x}{12}[/tex]
[tex]\longmapsto \sf \dfrac{1}{2}= \dfrac{x}{12}[/tex]
[tex]\longmapsto \sf \dfrac{1}{2}×12= \dfrac{x}{12}×12[/tex]
[tex]\longmapsto \sf x = 6[/tex]
Answer:
x = 6
Step-by-step explanation:
Hello!
The missing angle is 60°, and is found by subtracting 90° and 30° from 180°.
Using basic triangle theorems of a 30° - 60° - 90° triangle, we know that the leg opposite to 30°, x, is one-half of the hypotenuse.
So:
- x = 0.5(12)
- x = 6.
The value of x is 6.
The leg opposite to 60° is √3 times the leg opposite to 30°.
