Answer:
Step-by-step explanation:
We want to simplify;
We expand the bracket to obtain;
We now group the like terms to obtain;
We now simplify to get;
The correct answer is C
A trapezoid is isosceles if and only if
(1) The base angles are congruent
(2) The diagonals are congruent
(3) The opposite angles are supplementary
So the description does not guarantee that a trapezoid is isoceles for "Congruent bases".
15x^2+21x+6 that’s the answer
The greatest number of planes determined by four collinear points is ∞ , infinity
Answer:
b = 34°
Step-by-step explanation:
b + 115° + 31° = 180°

b = 180° - 146°
b = 34°
