Supplementary Angles Examples Solutions Videos Worksheets Games Math worksheets. examples, solutions, videos, worksheets, stories, and songs to help grade 6 students learn about supplementary angles. what are supplementary angles? two angles are supplementary if they add up to 180°. supplementary angles, when placed adjacent to each other, form a straight line, a 180° angle. Let one of the angles be x degrees. the other angle, which is supplementary to it, will be (90 x) degrees. for example, if one angle is 60 degrees, the supplementary angle is 180 60 = 120 degrees. understanding supplementary angles is essential in geometry and trigonometry, as they are used to solve various problems involving angles, such.
Supplementary Angles Worksheet Teacher Made Twinkl This part of our complementary and supplementary angles worksheets helps 7th grade and 8th grade students to use the fundamental property of supplementary angles and solve for x in either one or two steps. one step. two step. download the set. identifying complementary and supplementary angles type 1. First, since this is a ratio problem, we will let the larger angle be 8x and the smaller angle x. we know that 8x 1x = 180 , so now, let's first solve for x: $$ 9x = 180° \\ x = \frac{180°}{9} = 20° $$ now, the smaller angle is the 1x which is 1(20°) = 20° answer: 20°. Example 1: finding missing angle measures (adjacent angles) the two angles shown are supplementary. find the measure of angle x. x. determine which angles are supplementary. the question states that angles x x and y y are supplementary and equal 180^ {\circ}. 180∘. x y=180 x y = 180. Example 1: two angles are supplementary. find the other angle if one angle is 80°. solution: let the missing angle be x. x 80° = 180° …angles are supplementary. solving for x, we get. x = 100°. therefore, the measure of the other supplementary angle is 100°. example 2: two angles that are supplementary.
