Question

if the difference between two supplementary angles is 40degrees then find the angles​

Answer 1

Step-by-step explanation:

• Let the angle be x and it's supplement be (180-x)
• (180-x) -x = 40
• 180-2x = 40
• -2x = 40-180 = -40
• x = -40/-2 = 20
• angle = x = 20
• supplement = (180-x) = (180-20) = 160
