Answer:
x = 7
Explanation:
Triangle = 180˚ so
8x =56 , because x is 7. I know this bc it is a little bit more than 53 (you can tell just by looking at the triangle.)and it is impossible for it to be higher than 56, because angle c is more than 56. And I also checked it, so it is right.
e + d + c = 180
53 + 56 + c = 180
180 - 109 = 71 so
71 = c
The line segment equation thing:
A straight line segment is equal to 180˚ as well so...
14(7) + 5
98 + 5
103
angle J = 103
Check:
53 + 56 + 71 = 180
