Which sequence of transformations most likely occurred in order to map ∆ABC→∆A'B'C'? * Rotation 180 degrees
Reflection across the Y-axis --> Translation 3 units left, 3 units up
Rotation 90 degrees clockwise --> Reflection across the Y-axis
Rotation 90 degrees clockwise --> Reflection across the X-axis

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

addition

step-by-step explanation:

sina-sinb

cosb+cosa

tana-tanb

cos0+cos x pi/3

20tan

step-by-step explanation:

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
