Answer:
√13 ≈ 3.61
Step-by-step explanation:
The distance formula is applicable.
d = √((x2-x1)² +(y2-y1)²)
AD = √((0-2)² +(1-4)²) = √(4+9) = √13
AD ≈ 3.605513 ≈ 3.61
___
The trapezoid is isosceles, so AD and BC are the same length, 3.61.
Answer:
I believe it should be; 1/3, 0.85, 5/4
Answer:
The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles <em>inside</em> a triangle add up to 180°.

Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°
Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)
Ask in the comments below if you are not sure about something.
I hope that helps you! :D
