Step-by-step explanation:
k-(7) =k-7 upon 7 k- (k-7)upon 7 =0 k upon 4 -(k-7)=0
Use the Please Exuse My Dear Aunt Sally method. Add what's in the parentheses first. (30) times 3 (90) - 3 = 77 ! Wait actually you are correct! No mistakes here!

Then I would draw a line dividing one of those 90 degree angles into two 45 degree angles. Now I would erase the middle line and now you have a 135 degree angle hint 90 + 45.
