Question

Two supplementary angles are in ratio 4:5 find the angles

Answer 1

Answer:

80,100

Step-by-step explanation:

• sum of the ratio is 4+5=9
• 4/9×180,5/9×180
• 4×20,5×20
• 80,100
• there for the two angles are 80 and 100

Answer 2

Step-by-step explanation:

Let the angle be x

so angles will be 4x and 5x

(reason - given 4:5)

4x+5x=180 degree

(reason - supplementary angles)

9x=180 degree

x=180/9 =20 degree

4x=4*20=80 degree

5x=5*20=100 degree
