Question

Fig 11.49, what is the value of x?

Answer 1

Answer:

x = 60

Step-by-step explanation:

7y + 5y = 180 (l.p.)

12y = 180

y = 15

3y + 5y + x = 180

3x15 + 5x15 + x = 180

45+ 75 + x = 180

120 + x = 180

x = 60

Answer 2

Answer:

Step-by-step explanation: 7y + 5y = 180 (l.p.)

12y = 180

y = 15

3y + 5y + x = 180

3x15 + 5x15 + x = 180

45+ 75 + x = 180

120 + x = 180

x = 60
