tony examines two triangles. he wants to prove that if two pairs of corresponding angles other than the included angles is congruent. he plans to use inductive reasoning. which of the following (coming) best describes the problem with this approach? a. it requires a multi-step proof b. it depends on theorems and postulates c. geometric statements require geometric deduction d. a single couterexample will invalidate the proof

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 )
