Question

6. Write and solve an equation to find the value of x. (Example 3) 120° X (2x) ico​

Answer 1

Answer:

120° = 2(x)°

120/2 = x

60 = x

Step-by-step explanation:

120° = 2(x)° because the two lines cross forming an x shape and angles opposite to each other are always equal in lines forming x shapes. Hence you can form an equation as shown above and solve it for x. Since the above equation is a linear one you can simply solve it by bringing all the numbers to one side. since 2 is multiplied on the right hand side, when we bring it to the left it has to be divided.
