Answer:
m<DCB = 84°
Step-by-step explanation:
ABCD is a parallelogram since it has two sets of parallel sides.
Opposite angles in a parallelogram are congruent.
Consecutive angles in a parallelogram are supplementary.
<DCB is consecutive to <D.
m<DCB + m<D = 180°
m<DCB + 96° = 180°
m<DCB = 84°
Answer:
14%
Step-by-step explanation:
21, 28, and 35 are multiples of 7. So you can divide each number by 7 (in other words scaling the triangle down by a scale factor of 7).
It becomes 3,4,5, which is the base Pythagorean triple.
3^2 + 4^2 = 5^2
9 + 16 = 25
