Answer:
let the smaller angle be x then larger angle be x+42
now of angle of supplementary is 180°
therefore x+x+42=180
2x+42=180
2x=180-42
2x=138
x=138/2
x=69° answer
Answer:
let the smaller angle = x°
larger angle = x°+42°
It is given that the angles are supplementary angles.So the sum of angles will be 180°
=》larger angle + smaller angle = 180°
=》x°+x°+42°=180°
=》2x°+42°=180°
=》2x°=180°-42°
=》2x°=138°
=》x°=69°
Smaller angle = x°=69°
Larger angle = x°+42°=69°+42°=111°
The larger angle is 111° and the smaller angle is 69°.
