Explanation:

Ok 2 and 4 are vertical angles which means they are the same measure. That means since 2 is 47, then 4 is 47 also. 1 and 2 form a straight line, so they are complementary and add up to 180.

a1+a2=180

a1+47=180

a1=133

Remember 1 and 3 are vertical angles, meaning they are congruent (means equal). So, 1 and 3 are both 133.
