(10x -20) (6x + 8)° what is the value of x​

Mathematics
1 answer:
Hoochie [10]2 years ago
7 0

Answer:

X=12

Step-by-step explanation:

Add the two equations together and equate them to 180 due to the geometrical reason that angles on a straight line add up to 180.

10X-20+6X+8=180 (collect like terms)

10X+6X=180-8+20

16X=192 (Divide both sides by 16)

X=12

Hope that helps :)
