Answer:
A. 45 and 135
Step-by-step explanation:
Recall: two angles on a straight line forms a linear pair. The pair sum up to 180°.
Thus:
✔️c° + 3c° = 180°
4c = 180
Divide both sides by 4
4c/4 = 180/4
c = 45°
✔️3c = 3(45) (substitution)
= 135°
Answer: The angle of elevation X = 62.7 degrees
Step-by-step explanation: Please refer to the attached picture for details.
The ramp rising from the ground is given as line XZ which is 18 feet. Also it rises 16 off the ground which is also given as line YZ. The angle of elevation of the ground, that is, angle X is the angle formed at point X where the ramp begins to rise. We shall apply the trigonometric ratio to solve for angle X, having been given two sides of the right angled triangle. The side YZ is the line facing the reference angle (opposite) while the side XZ is the line facing the right angle (hypotenuse).
SinX = opposite/hypotenuse
SinX = 16/18
SinX = 8/9
SinX = 0.8888
From your calculator or table of values,
X = 62.7339
Rounded to the nearest tenth of a degree,
X = 62.7 degrees
For the first question, the most appropriate answer is D, since it is when the distance ran remains the same, but the time is still ticking. Unless the time stops, the graph should always be going in an upwards direction.
For the second question the most accurate answer is A
For the third question, nonlinear decreasing seems to be the most appropriate answer since it is going down at a non addition/subtraction rate.
For the fourth question I am not too sure, but I strongly believe that the correct answer is D, since it is the only one that seems to have a negative direction to it!
And for the fifth and final question, the correct answer would certainly be C, It has a constant rate of change.
I really hope this helps you with your homework, and if you need me to do any explaining, please let me know and I will do so! Thank you!
