Answer:
you can do it
Step-by-step explanation:
The unknown values are as follows:
a = 48.7°
b = 51.43
c = 12.16
d = 122.39

<h3>Properties of a right angle triangle:</h3>One angle is equals to 90 degrees
- The sides and angle can be calculated using trigonometric ratios
Therefore,
sin 72.3° = opposite / hypotenuse
sin72.3° = 49 / b
b = 49 / sin 72.3
b = 49 / 0.95266148125
b = 51.4348495916
b = 51. 43
a = (180 - 90 - 23.6) - (180 - 72.3 - 90)
a = 66.4 - 17.7
a = 48.7°
tan 23.6 = opposite /adjacent
tan 23.6 = 49 / c
c = 49 / tan 23.6
c = 112.158945248
c = 12.16
sin 23.6 = opposite /hypotenuse
sin 23.6 = 49 / d
d = 49 / sin 23.6
d = 49 / 0.40034903255
d = 122.39

Answer:
Graph C represents a decreasing function.
Step-by-step explanation:
Graph A: Since y does not change when x increases from 0 to 6, this graph (a horizontal line) represents a constant function. REJECT this choice.
Graph B: The line connecting (0, 0) to (6, 6) is a straight line with slope +1; it's an increasing function. REJECT this choice.
Graph C: As we go from (0, 5) to (6, 0), y decreases by 5. Thus, this is the correct answer choice.
Graph D is a vertical straight line; its slope is undefined. REJECT this choice.
