Question

I keep getting the wrong answer for some reason, help please

Answer 1

In order to find the measure of angle A we have the next equation. Remember that the sum of the interior angles of a triangle is 180°

`(3x-6)+(8x+4)+(180-130)=180`

Then we sum like terms

`11x+48=180`

Then we isolate the x

`11x=180-48`
`11x=132`
`x=(132)/(11)`

`x=12`

For angle A

angle A= 3x-6=3(12)-6=30°

angle A=30°
