Question

In the given below Figure AOB is a straight line. find the value of X ​

Answer 1

Answer:

60°+5x+3x=180 (angle sum property)

60°+8x=180

8x=180-60

8x=120

x=120/8

x=15

Answer 2

Step-by-step explanation:

in figure,

angle AOB = 180(straight line)

According to the problem....

60 + 5x + 3x = 180. (straight line)

60 + 8x = 180

8x = 180 - 60

8x = 120

x = 120/8

x = 15

$\huge{x = 15}$

now,

3x = 3×15 = 45

5x = 5×15 = 75
