A is c and a because it's on the left of 0.
B is b and d because it's on the right of 0.
Answer:
x = 
Step-by-step explanation:
I would subtract 5x and 2 on both sides to get x^2 - 5x - 2 = 0, and using the A = 0, B = -5, and C = -2 to plug it into the quadratic equation which is
*Ignore the A please I cannot get rid of it.*
First we have to find supplement angle of 139° :180° - 139° = 41°c = 180° - ( 77° + 41° ) 180° - 118° = 62°Also b and c are the supplement angles:b = 180° - 62° = 118°Angle x is the angle between angles 36° and 77°, such that:36° + x + 77° = 139°x + 113° = 139°x = 26°a + b + x = 180°a + 118° + 26° = 180°a = 180° - 144°a = 36°Answer: D. a = 36°, b = 118°, c = 62°
