Answer:
x = 28
m∠ACD = 68°
Step-by-step explanation:
∠BAE ≅∠DAC because they are vertical angles
∠ACD = 180 - 124 = 56°
to find 'x': 56 + 2x + (180 - 4x) = 180
236 - 2x = 180
-2x = -56
m∠ACD = 180 - 4(28) = 180 - 112 = 68°
Step-by-step explanation:35x
x= 3 +, 3 -
You use the quadratic formula to get x=
Then you simplify and get the answers x= 3 +, 3 -
