Answer:
<u>28</u> cm
Step-by-step explanation:
side opposite of 30° = x = shorter leg / opposite.
side opposite of 60° = x√3 = adjacent.
side opposite of 90° = 2x = hypotenuse.
Answer:
x ≤ a → x ∈ (-∞, a]
x < a → x ∈ (-∞, a)
x ≥ a → x ∈ [a, ∞)
x < a → x ∈ (a, ∞)
--------------------------------------
Therefore:
x ≥ 7.8 → [7.8, ∞)
x < 7.8 → (-∞, 7.8)
x ≤ 7.8 → (-∞, 7.8]
x > 7.8 → (7.8, ∞)
