Answer:
The length of side x = 4 units.
Explanation:
Given
The angle Ф is 30°.
The opposite side of angle 30° is 2.
To determine
The length of hypotenuse x = ?
Using the trigonometric ratio
sin Ф = opposite / hypotenuse
substitute Ф = 30°, hypotenuse = x and opposite = 2
sin 30° = 2 / x
1/2 = 2/x ∵ sin 30° = 1/2
x = 2 × 2
x = 4 units
Therefore, the length of side x = 4 units.
