Question

two adjacent a angles on a strite line are in ratio 5:4. find the angles​

Answer 1

Hope this answer may helpful for you ☺️

Answer 2

Step-by-step explanation:

The adjacent angles on a straight line are in the ratio of 5:4.

Let the adjacent angles be 5x and 4x.

Now, 5x+4x=180°

{ Since adjacent angles on a straight line = 180°}

9x=180

$x = \frac{180}{9}$

⇒x=20

The adjacent angles are as follows:

5x = 5×20=100° 4x=4×20=80°
