Answer:

a = 32

Step-by-step explanation:

Step 1: Understand the question

The 2 angles inside are supplamentary angles which means they add up to 180

Step 2: Set up the equation

If the 2 angles added up equal to 180 you can create an equation that states

[tex](2a+7)+109=180[/tex]

Step 3: Solve for the variable

[tex](2a+7)+109=180\\2a+7+109\\2a+116=180\\2a=64\\\frac{2a}{2}=\frac{64}{2}\\a=32[/tex]

Step 4: State your answer

Therefore the value of "a" is 32
