Open circle means that it doesn t include the point in this case 8 it s moving to the right so to the + zone so x>8
Answer:
7/9
Step-by-step explanation:
if you add the two numbers you will get 7/9
All the angles in a triangle equal 180 degrees so 128 + (5x+10) + 9x = 180
Group the like values to get 138 + 14x = 180
Subtract 138 from 180 to get 14x = 42
Divide 42 by 14 to get x = 3
Therefore x = 3
The answer is that they are congruent.
