I thought of it as answering a regular equation and imagine it's equal signs but when your done solving you with have like ex x<5 and where ever the butt of the arrow is pointing is where the lines goes if there's ano equal sign below it then it is includive
X = 45.
Since opposite exterior angles are congruent, you can set the 2 values equal to each other. When you solve for x, you should get 45.
The first ratio is 1:4 so if x is 6 then 6x4 is 24 your answer is 24.
To find the decimal, all you need to do is take the number on top and divide it by the one in the bottom. 129/3930=0.03
