BAC=ABD. therefore ABD = 20°
BDA = 180° - 20° -20° = 140°
BDC = 180° - 140° = 40°
BCD = 180° - 40° - 20° = 120°
Answer:
-
Step-by-step explanation:
substitute y into the equation. -3x + 1/2(6x + b) = -3. Multiply 1/2 by 6 and b, then add it to -3x for like terms. After that you should be able to find Y.
Answer:
m = variables
+4 = Coefficients
-7 = Coefficients
and 2 and 6 are Constants
