Just simply use the calculation of a trapazium.
[ (6+7) + 21 ][6]
---------------------
2
that's the formula of a trapazium. add the top length and bottom length, multiply it by the height and divide all of them by 2.
now the answer should be A, 102.
C and A are congruent since they are alternate interior angles.
Angles B and A are a linear pair. Linear pairs are supplementary as well. Since we know A is 44, all the have to do is 180-44 . That equals 136.
In short, A=44 and B=136
Answer:
A, a rhombus has all the properties of a square.
Step-by-step explanation:
Not all quadrilaterals will be the same
Equation of circle : (x-h)² + (y-k)² = R², where h and k are the coordinates of the circle and R, THE RADIUS
Center coordinates (5,-4), hence
(x-5)² + (y+4)² =R²
Now let's calculate R. Just replace x and y by the coordinates (-3,2)
(-3-5)² + (2+4)² = 10², so the Radius is equal to 10 and the final shape:
(x-5)² + (y+4)² = 100
