Ответ:
50
Step-by-step explanation:
opposite angles are equivalent so set them equal to each other and isolate x
2(x+10)=(3x-30)
2x+20=3x-30
20+30=3x-2x
50=x
Ответ:
The value of x is 50.
Step-by-step explanation:
Hi, since the opposite angles are equal we can assume:
2(x+10) = (3x-30)
So, solving for the variable "x":
2(x+10) = (3x-30)
First, we apply distributive property:
2x+20=3x-30
Adding alike terms and isolate x:
20+30 =3x-2x
50=x
The value of x is 50.
Feel free to ask for more if needed or if you did not understand something.
