Angles BAC and Angle CAD are supplementary angles. Find the measures of each angle if the measure of Angle BAC is 10x + 16 and the measure of Angle CAD is 7x + 8. Round angle measures to the nearest tenth

Answer 1

As you know, Bob, supplementary means they add to 180°

10x+16 + 7x+8 = 180
17x + 24 = 180
17x = 156
x = 9.176

BAC = 10*9.176+16 = 107.8
CAD = 7*9.176+8 = 72.2
