Question

I got confused I add or multiply 30 3 times? Or am i wrong

Answer 1

Answer:

30=3x

so divide 30 by 3 and you'll get x

Answer 2

Answer:

10

Step-by-step explanation:

You equate. The two angles are equal. The figure is called vertically opposite.

Vertically opposite angles are equal.

3x = 30                          Now you divide by 3

3x/3 = 30/3

x = 10

And 10 is your answer.
