Answer:
Step-by-step explanation:
Supplementary angles add up to 180
∠1 + 50 = 180
∠1 = 180 - 50
∠1 = 130
∠3 +50 = 180 {Supplementary}
∠3 = 180 - 50
∠3 =130
⇒∠1 = ∠3 = 130
I have to think this through.... I will get back later 2.222
The set of odd numbers between zero and ten is:
[ 1, 3, 5, 7, 9 ]

Answer:
Through any three non-collinear points, there exists exactly one plane. A plane contains at least three non-collinear points. If two points lie in a plane, then the line containing them lies in the plane. If two planes intersect, then their intersection is a line.

Multiply both sides by 3:

Recall that 21/5=4.2 to claim the correct answer.
