Question

the given figure, it is given that AOB is a straight line and 4x= 5y
what is the value of x?​

Answer 1

Answer:

1. 4x=5y
2. as it is a straight line 4x+5y=180°
3. 5y+5y=180°
4. 10y=180°
5. y=180÷10
6. y=18
7. 4x=5y
8. 4x=5×18
9. 4x=90
10. x=90÷4
11. x=22.5

Answer 2

Answer:

100

Explanation

Because,

Let the measure of its supplement be 4x and 5y.

Then,

= x+(4/5)x = 180

= (5x+4x)/5 = 180

= 9x = 180×5

= 9x = 900

= x = 900/9

= x = 100
