For line b, d, and e, line dis parallel to line e and m_1 = 81°.
Part A: In complete sentences, explain the relationships between all pairs of special angles 1, 2, 3 and 4 created by
transversal line band parallel lines d and e.
Part B: for the given diagram, use the measure of The following special angle relationships are created by transversal
line b and parallel lines d and e: 1 to find the measures of <2, <3 and <4

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 )
