Answer 2

Hello:

Let's consider what the question asks for:

--> find the value of 'x'

The two angles given are supplementary

--> as together

--> they form a straight line which represents a total of 180 degrees

--> in mathematical form

`(x+19)+(7x+9)=180\\x+19+7x+9=180\\8x+28=180\\8x=152\\x=19`

Answer: 19
