Question

GD Find two supplementary angles whose ratio is 7:8.
6. An angle is equal to two-seventh of its supplement. Find the angle.
In the adjoining figure, name all the pairs of adjacent angles
which form a linear pair.
7.
O
The difference between two supplementary angles is 54". Find the two angles.​

Answer 1

= GD - 7:8

(GD IS A SUPPLEMENTARY  ANGLE)

G + D = 180°

Angle G = 7/15 * 180° = $\frac{7}{15}$ * 180° = 7 * 12 = 84°

Angle D =  8/15 * 180° =  $\frac{8}{15}$ * 180° = 8 * 12 = 96°

________________________________________________

An angle is equal to = 2/7th of supplement

                                   = $\frac{2}{7}$ of 180°

                                   = 51.4
