Question

two supplementary angles are in the ratio 11 : 7 then find the angles

1 point

110 degree, 70 degree

120 degree, 60 degree

130 degree 50 degree

70 degree 110 degre

​

Answer 1

Answer:

11x + 7x=180

18x = 180

x = 180/18

= 10 degrees

11x= 11×10 = 110 degrees

and 7x = 7×10 = 70 degrees

therefore the angles are

110 degrees and 70 degrees.
