Answer:
28° (Answer A)
Step-by-step explanation:
Note that tan t = 8/15 = 0.533
Applying the inverse tangent function, we get
t = arctan 0.533 = 0.4900 radian
Mult. this by the radian-degree conversion factor results in: 28.072°
and when rounded off to the nearest degree, the measure of angle T is 28° (Answer A)
The third one, this is because you take your y2 and y1 values (y2=0 and y1=9 because these are the two y values given to you from each coordinate) and subtract 0-9. then you do the same, but with the x2 and x1 values. so your x1 value is 3 and your x2 value is 0, so you subtract 0 from 3. divide your second answer from the first answer, to get a gradient of -1/3 x. now using the first coordinate (0,9) you know that the y coordinate is 9. as the x value =0, we know that the line is passing through the y axis at 9 so 9 is your y intercept. this gives you the equation -1/3x+9. hope this helped and wasn't too confusing!
Answer:
heyy, how was your weekend?
Answer: She is incorrect because 0 + 0 = <u>0</u>
