Answer:
(c) 52.0
Step-by-step explanation:
The angle whose cosine is 8/13 is found using the inverse cosine function:
y° = arccos(8/13) ≈ 52.0°
y ≈ 52.0
__
The calculator button to compute this value is probably labeled cos⁻¹. You may need to access the function using a <em>Shift</em> or <em>2nd</em> key. The calculator must be set to degrees mode to prevent the answer from appearing in radians or grads. If you use a spreadsheet, your formula may look like ...
=DEGREES(ARCCOS(8/13))
You see how many times 4 can go into 25 witch is 6 not 7 because 7 x 4 is28 and 28is bigger than25 so the answer is and 1/4 is25 cence so the answer is 4.25
Answer:
i think it's undefined
Step-by-step explanation:
It means that the tails never actually *touch* the x-axis, but it gets infinitesimally close to it.
