Question 96958
The diagonal brace on a rectangular gate forms an angle with the horizontal side with degree x and an angle with the vertical side with degree measure 2x – 3. Find x. 
x + (2x – 3) =180
3x – 3 = 180
3x = 183
x = 61
Answer: x = 61 
Check : 61 + (2*61-3) = 180
61 + 122-3 = 180
183-3=180
180=180
