5. What if you wanted to figure out the angle at which the sun's rays hit the earth? The sun's rays hit the earth such that the tangent rays determine when daytime and nighttime are. The time and Earth's rotation determine
when certain locations have sun. If the arc that is exposed to sunlight is 178 degrees, what is the angle at which
the sun's rays hit the earth (x)?

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 )
