Step-by-step explanation:
Answer: It has no solution.
Step-by-step explanation:
3x - 12 - 4 = 3x + 4 - 4
3x - 8 = 3x
3x - 8 - 8 = 3x - 8
we can't subtract 3x-8
Doesn't add up; they need to have one solution or more for it to work.
<span>sin 90° = 1
</span>
cos 0° = 1
There's a simple formula : <em>sin θ = cos (90°- θ)</em> or <em>cos θ = sin (90°- θ) </em>
So : cos 0° = sin (90° - 0°) = sin 90° = 1
Cos35= y/15
y= 15cos35
y= 12.3 cm
