Answer:
Step-by-step explanation:
9*60+36= 540+ 36= 576 minutes
so it is = 576/ 60 hours
Answer: -45° = -(π/4)
<u>Step-by-step explanation:</u>
sin x + cos x = 0
sinx = -cos x <em>subtracted cos x from both sides</em>
<em>divided cos x from both sides</em>
tan x = -1 <em>simplified fraction</em>
tan⁻¹ (tan x) = tan⁻¹ (-1) <em>applied inverse tan to both sides</em>
x = tan⁻¹ (-1) <em>simplified</em>
x = -45°
<u>Easier method:</u>
sin x = -cos x
At which points are cos x and sin x opposites?
- <em>In Quadrant II at 135°</em>
- <em>In Quadrant IV at 315 (which equals -45°)</em>
Inverse tan is only valid in Quadrants IV and I so the answer is -45°
3.1 or if it didn't have a 3 in ones it would be 0.1
Answer:
23.4 so 23 or 24 :)
