•sum of the angles in a triangle = 180°
•sum of the angle in a quadrilateral = 360°
•opposite angles are equal
•for two parallel lines and a transversal, corresponding angles are equal, and alternate angles are equal.
•If it already has an angle for a triangle subtract that by 180 and divide it by two you have the other two angle, if you already have two angles on a triangle add those together and subtract from 180 thats the last angle, same for a quadrilateral but you subtract by 360 instead.
Point E is correct answer
The distance of A from the origin.
√(5²+3²+(-2)²)= √(25+9+4)
=√38
=6.2
The distance of B from the origin
√(2²+(-4)²+8²=√(4+16+64)
=√84
= 9.2
Answer:
The right solution is "0.196".
Step-by-step explanation:
The given values are:
