Question

80 % of an angle is the supplement of 140 degree . Find the Angle

Answer 1

measure of angle is 60 degrees

Answer 2

Let that angle be x

supplement of 140 = 180 - 140

= 40

so by the condition given in your question we get equation

80 % × x = 40

80/100 × x = 40

x = 40 × 100 /80

x = 50

so the angle is of measure 50
