∠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:
b
Step-by-step explanation:
The correct answer is (B). The correction will decrease the mean because 8 is less than 18 and will decrease the standard deviation because the value, 8, is closer to the mean than the value 18.
Answer: x= -3
Step-by-step explanation: First you add 4.2x to both sides to get: 1.8+0.5x= 0.3. Then you subtract 1.8 from both sides and get: 0.5x=-1.5. Lastly, you divide by 0.5 both sides and get x=-3
