4 sin(<em>x</em>) + 9 cos(<em>x</em>) = 0
4 sin(<em>x</em>) = -9 cos(<em>x</em>)
tan(<em>x</em>) = -9/4
<em>x</em> = arctan(-9/4) + <em>nπ</em> … … … (in radians)
or
<em>x</em> = arctan(-9/4) + 180<em>n</em> ° … … … (in degrees)
where <em>n</em> is any integer.
I'm guessing you're solving for <em>x</em> over some domain, probably 0° ≤ <em>x</em> < 360°. In that case, you would have two solutions for <em>n</em> = 1 and <em>n</em> = 2 of
<em>x</em> ≈ 113.96° and <em>x</em> ≈ 293.96°
Answer:
The answer is A
Step-by-step explanation:
Just trust me
A) 2/3 divided by 5/1
= 2/3 X 1/5
= 2/15 of the book
B) 14X5=70
1/3
2/3
3/3
70+35= 105 pages
10 x 20 = 200
30 + 20 = 50
200/50 = 4
answer
