Angle 5 and Angle are consecutive interior angles. To find the coterminal angles to your given angle, you need to add or subtract a multiple of 360° (or 2π if you're working in radians). Vertical Angles. 4 Angles that are opposite one another are VERTICAL ANGLES. A vertical angle is an angle formed by two connected lines in the vertical plane*, that is, between a low point and two higher points.Since these angles are in the vertical plane, the lines that form them will usually be lines of sight. Now plug –5 and 15 into the angle expressions to get four of the six angles: To get angle 3, note that angles 1, 2, and 3 make a straight line, so they must sum to 180°: Finally, angle 3 and angle 6 are congruent vertical angles, so angle 6 must be 145° as well. find the value of the angle.
