Answer:
A= 30
Step-by-step explanation:
This requires several steps.
First, you need to find the 2 other missing angles.
One can be found easily by substracting 130 from 180
so 180-130 = 50
The other angle is the same as 8x+4
Now set up your equation
180=3x-6 + 8x+4 +50
180 = 3x + 8x -6 + 4 +50
180+6-4-50 = 11x
132 = 11x
132/11 = x
12 = x
Now plug in 12 for x in your angle A
A=3x-6
A=3 * 12 - 6
A=36 - 6
A= 30
Answer:

Answer:
4(3x +8)
Step-by-step explanation:
You are being asked to factor 4 from each of the terms of the expression and use the distributive property to show the result.
12x +32
= 4(3x) +4(8)
= 4(3x +8)
The numbers that go in the boxes, left to right, are ...
4, 3, 8
