Y - 20 and Y + 30 are the measures of complementary angles find the measure of each angle
Y - 20 and Y + 30 are the measures of complementary angles find the measure of each angle The of is 900. •fbercfore, they arc
ample Find the mea s of the
complement Of an angle Of
measure 70 e ?
Solution; Let the measure of the
complementary angle be x.
70 •x -90
70 x-70 -90-70
x 200
The measure of the complement
of an angle of mcasure 700 is 200.
