∠1 ≅∠3 = 130º
1) Gathering the data, accordingly to what's been told we can write:
∠1 + ∠50º = 180º <em>Definition of two supplementary angles</em>
∠50 +∠3 = 180º
2) Then we can evaluate:
∠1 + ∠50º = 180º <em>Subtract ∠50º from both sides</em>
∠1 = 180º -50º
∠1 = 130º
∠50 +∠3 = 180º
∠3 = 180º-50º
∠3 = 130º
3) Hence ∠1 ≅∠3 = 130º because the definition of supplementary angles is the same.
Answer:
23.6 or A
Step-by-step explanation:
We have sin already. 8/20
We use inverse sin of 0.4 (8/20)
The answer of inverse sin is 23.57817848
or 23.6

Answer:
20%
Step-by-step explanation:
If we think of the circle as 1, and each piece 1/5, and since we know that 1/5 = 20%, we can conclude that each piece takes up 20% of the circle.
