Question

2 adjacent angles on a straight line are 5x degree and 4x degree find the angle​

Answer 1

Answer:

Step-by-step explanation:

let first angle = 5x

and second angle = 4x

we know, sum of two adjacent angles =180°

so,

5x + 4x = 180°

9x = 180°

x = 20°

so, first angle = 5x = 5×20=100°

second angle = 4x =4×20= 80°

Answer 2

Answer:

Step-by-step explanation:sum of adjacent angles is 180

So,

4x+5x=180

9x=180=x=180/9=20

X=20

So, first angle =5x=5*20=100

Second angle =4x=4*20=80
