C the third one
Step by step
Supplementary angles definition: They add up to 180°
There are several ways to prove a parallelogram:
1. Opposite sides theorem converse
2. Opposite angles theorem converse
3. Parallelogram diagonals theorem converse
4. Parallel congruent sides theorem
∠P + ∠Q = 180° --1
∠P + ∠S = 180° --2
1: ∠P = 180° - ∠Q
Sub 1 into 2:
180° - ∠Q + ∠S = 180°
180° + ∠S = 180° + ∠Q
∠S = ∠Q
Or you can try saying the opposite sides are parallel, since they are interior angles and those are straight lines
Answer: 10 years
Step-by-step explanation:
1720=960(1+0.061/12)
C.
if you multiply the 4 on each numbers inside of the parentheses then you’ll get ‘20c-8d’
35/8 = 4.376 5/3 = 1.666… 4.376/1.666…
Therefore 2.625 pieces
