Answer:
x = 50
Step-by-step explanation:
We are given a diagram showing two vertically opposite angles and we are to find the value of x.
We know that when two lines intersect each other, vertically opposite angles are formed which are equal to each other.
Therefore, we can write them as:
[tex] 2 ( x + 1 0 ) = 3 x - 3 0 [/tex]
[tex] 2 x + 2 0 = 3 x - 3 0 [/tex]
[tex] 3 x - 2 x = 2 0 + 3 0 [/tex]
x = 50
