Find all solutions of the equation. 4 cos(theta) - 7 sin (theta) + 2 = 0 sec(theta) (2cos (theta) -squareroot 2) = 0 5 sin (theta) - 2 = 0 cos (2 theta) = cos^2(theta) - 1/2

Bis the answer! hope this

1. 3/6 or 1/22. 1/123. 1/84. 1/105. 2/12 or 1/6

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 )
