Angle D is equal to Angle B because AB and DE are parallel to each other.
AD is a straight line so the (2) 2x angles and 72 degrees need to equal 180.
Setting up the equation you have:
2x + 2x + 72 = 180
Simplify:
4x + 72 = 180
Subtract 72 from each side:
4x = 108
Divide both sides by 4:
x = 108 / 4
x = 27
<span> The answer
2 (x + 3) = 2x + 6</span>
Answer:
Step-by-step explanation:
(14 + 7)/2 = 21/2= 10.5
(-2 + (-8))/2= -10/2= -5
Midpoint(10.5, -5)
8x - 2y = -8
-5x + 2y = -1
3x = -9
x = -3
Knowing that a square gives the optimum area;
120=s²
√120=s
√2×2×2×5×3=s
2√2×3×5=s
2√30=s
Therefore, the length should be ≈10.95"
Hope I helped :)
