The four interior angles of a quadrilateral always add to 360<span>°, so the answer is 98</span>
Answer:
All real numbers except the number zero
Step-by-step explanation:
we know that
Observing the graph
The range is the interval
(-∞,0) U (0,∞)
The number zero is not included in the range
therefore
All real numbers except the number zero
Recall the double-angle identity,
sin²(<em>x</em>) = (1 - cos(2<em>x</em>)) / 2
Now if sin(12°) = <em>k</em>, then
<em>k</em> ² = sin²(12°) = (1 - cos(24°)) / 2
→ cos(24°) = 1 - 2<em>k</em> ²
