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=\frac{132}{11}$

$x=12$

For angle A

angle A= 3x-6=3(12)-6=30°

angle A=30°
