The difference between two supplementary angles is 20 find the angles ( hint pair of angles whose sum is 180 are called supplementary angles​

Answer»

Step-by-step explanation:

LET /_a = X °

so according to question /_b = (x+20)°

now , we know that , sum of two supplementary angles =180°

====> /_ a + /_b = 180°

=> x + (x+20) =180

=> 2x +20 = 180

=> 2x = 160

=> x = 80°

THEREFORE, measure of each acute is :

===> /_a = x = 80°

♦ Acute ANGLE is greater than 0 but less than 90... so we get only one..

another angje /_b = x+20 = 100°

♦ which is not acute ..it is obtuse
