Answer:
x = 14
Step-by-step explanation:
∠ DCA and ∠ BCF are adjacent angles and sum to 180° , then
∠ DCA = 180° - 124° = 56°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
6x is an exterior angle , then
6x = 2x + 56 ( subtract 2x from both sides )
4x = 56 ( divide both sides by 4 )
x = 14
Answer:

Set up the equations.
Answer:
D = sqrt[ (2-4)^2 + (7- (-1))^2] = ~8.2
Step-by-step explanation:
D = sqrt[ (Fx-Gx)^2 + (Fy- Gy)^2]
376.64-109.38=267.26
The tenth place is the first number after the decimal. 5 and up make the number in front go up. Since we have a 6 here, the 2 goes to 3.
267.26 rounded to the nearest tenth is 267.3
