Question

two supplementary angel are in the ratio 4 is to 5 find the angel ​

Answer 1

Answer:

Since sum of two supplementary angles is 180°

Let let the angles be 4x and 5x

Therefore,

4 x + 5 x = 180 °

=> 9x = 180°

=> x = 180°/9

=> x = 20°

Therefore,

4x = 4×20° = 80°

5x = 5×20° = 100°

Hope this helps mate ☺️.

Answer 2

Let two angles be 4x and 5x

Sum of supplementary angles is 180

4x+5x=180

9x=180

x=

9

180

=20

So, one angle = 4x=4×20=80

Another angle = 5x=5×20=100

Larger of two angle is 100
