Worksheet #19 Proportions Write each proportion.52 14 24 5 12 Find the measure of the supplement of each angle using degrees, minutes, and seconds. Find the measure of the complement of each angle using degrees, minutes, and seconds.Angle Measure Degree – Unit that angles are measured in 1/360th of a circle Symbol: ° reads ‘the measure of angle PQR’ Reason why there is no degree sign, because it is a measure and not a measurement m PQR.Do Now Find the measures of the three angles.

Worksheets > Math > Grade 5 > Geometry.Hence x + 144 = 180° Solve for x x = 180 - 144 = 36° The sum of angles x, y and z of the triangle is equal to 180° x + y + z = 180 Substitute x and y by their values found above. Hence y + 56° = 180° Solve for y y = 180 - 56 = 124° Angle x and angle of measure 144° are supplementary. Angle y and angle of measure 56° are supplementary.
