Which series of transformations will move the triangle and quadrant one onto the similar triangle in quadrant three A. reflection across the x-axis and translation six units up.

B. translation 6 is down and reflects across the y axis.

C. rotation of 90 clockwise and reflection across the y-axis.

D. translation 6 is down and rotation 90 units counterclockwise.

Wow. that is a really cool question.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
