Can you help me please?​
Naddik [55]

Answer:

x=70, which is D.

Step-by-step explanation:

As you can see, (2x-30) and x are different angles, but add up to 180. So, we can make an equation that looks like this:

(2x-30)+x=180

2x-30+x=180

3x=210

x=70

                                                     :)
