Answer:

x = 60

2x = 120

2x + 30 = 150

2x - 30 = 90

Step-by-step explanation:

2x + 2x - 30 + 2x + 30 = 360

2x + 2x + 2x + 30 - 30 = 360

6x + 0 = 360

6x = 360

x = 360 / 6

x = 60

= 2 x 60

= 120

2x + 30

= 120 + 30

= 150

2x - 30

= 120 - 30

= 90

julsineya [31]

Answer:

The abbreviation of the postulate which can be used to support the conclusion is SAS ( Side Angle Side )

Step-by-step explanation:

Given : WS = NT, AS = OT, S = T

Now, two sides are given to be equal and one angle

So, the similarity postulate which can be used to support the conclusion can be SAS ( Side Angle Side ). But for this postulate to be used, The angle must lie between the two equal sides.

So, the abbreviation of the postulate which can be used to support the conclusion is SAS ( Side Angle Side )
