Which one is correct ?

Give the two exterior angles of 133 and 142, we can deduce that the interior angles are 47 and 38, respectively. In fact, if and are the interior and exterior angles, respectively, we have

Now, the interior angles of a triangle sum up to 180 degrees. Since we already have angles of 47 and 38 degrees, the missing angle is

Which implies

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
