The angle of interest is the one at the end of the shadow looking up toward the flagpole. Thus the length adjacent to the angle is that of the shadow, 22 ft. The length opposite the angle is the height of the flagpole, 45 ft. The tangent of the angle is the ratio of the opposite length to the adjacent one.
... tan(angle) = (45 ft)/(22 ft)
... angle = arctan(45/22) ≈ 63.9° . . . . . matches selection A.
Answer: The equation that describes proportional relationship is y = 0.75x
Constant of proportionality is 0.75
Step-by-step explanation:
4y = 3x
Divide both sides by 4 to get the value of y
y = 3x/4
12y = 9x
Divide both sides by 12 to get the value of y
y = 9x/12 divide the numerator and denominator by a common value of 3
y= 3x/4
y = 0.75x
The equation that describes proportional relationship is y = 0.75x, meaning y is inversely proportional to x, as x increases, y also increases.
Constant of proportionality is 0.75
I hope this helps.
Always true.
2(x+3) =2x +6 Times 2.
2x+6=2x+6
