Answer:

a = 34°

Step-by-step explanation:

1. We know that the straight line is a straight angle (180°), and the right angle is worth 90°.

2. This means that a + 90 + 56 = 180.

3. (Solving equation above).

Step 1: Simplify both sides of the equation.

  • [tex](a)+(90+56)=180[/tex]
  • [tex]a + 146 = 180[/tex]

Step 2: Subtract 146 from both sides.

  • [tex]a+146 - 146 = 180 - 146[/tex]
  • [tex]a = 34[/tex]

Step 3: Check if solution is correct.

  • [tex](34) + 90 + 56 = 180[/tex]
  • [tex]124 + 56 = 180[/tex]
  • [tex]180 = 180[/tex]

Therefore, a = 34°.
