Answer:
48√3 cm
Step-by-step explanation:
I'm assuming that ∠A = 30°, ∠R = 60°, and ∠Y = 90°.
The sides of a 30-60-90 triangle are in the ratio 1:√3:2.
RY is opposite the 30° angle and has length 48 cm.
AY is opposite the 60° angle, so the length of AY = 48√3 cm.
Answer:
C.
Step-by-step explanation:
Alan and his classmates found that the line of best fit through the data had the equation
The slope of this line is
If a line would intersect this line of best fit at right angles, then the two lines are perpendicular to each other.
The slopes of perpendicular lines are negative reciprocals of each other,
Hence that line must have slope
Therefore we look for a line whose slope is from the given options.
That line is the third option
