The three angles of the triangle = 180 o

(180 -122)   +   (180 -118)    +  3y = 180

 

When you find y    then     3y +  (x-25)  = 180    (straight line)    to slove for x

3y +  (x-25)  = 180  Wrong!!!

 

3y + 180-118 + (x - 25) = 180  smiley

(180 -122)   +   (180 -118)    +  3y = 180, solve for y

     58            +        62             + 3y = 180

3y = 180 - 58 - 62 =60

y =20 degrees

 

3y + 180-118 + (x - 25) = 180, solve for x

3*20  +  62    + (x - 25) = 180

x - 25 = 180 - 60 - 62

x - 25 = 58

x =58 + 25

x = 83 degrees
