At what angle do two straight lines intersect if the sum of the degree measures of two from four formed angles is exactly 290 degrees?
Since when two straight lines intersect, two pairs of vertical angles are formed, then the angles of the first pair will be equal to 290˚: 2 = 145˚, that is, 145˚. Find the second pair of vertical angles 180˚ – 145˚ = 35˚, that is, each angle of the second pair is equal to 35˚. From this we can conclude that two straight lines intersect at an angle of 35˚.
Answer: two straight lines intersect at an angle of 25˚.
