Yes. 450 ÷ 9 = 50, 450 ÷ 5 = 90, 450 ÷ 10 = 45
Answer:
3i-1
Step-by-step explanation:
2+3i-3
3i-1
It can be 8:12 or as a fraction it’s 8/12
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
