Answer:
∠3 = 140°
Step-by-step explanation:
∠4 = 40°
∠4 = ∠1 <u><em>(vertical angles)</em></u>
∠1 = ∠2 <u><em>(alternate angles)</em></u>
∠2 = 40°
So,
∠2+∠3 = 180 <em><u>[Angles on a straight line add up to 180°]</u></em>
40 + ∠3 = 180
∠3 = 180-40
∠3 = 140°
Answer:
2
Step-by-step explanation:
5 x 2 = 10
5 x 3 = 15 > 14
therefore...
there are 2 teams of 5
Yes 15/16 is greater then 1/8
Answer:
x = 49
Step-by-step explanation:
180-131=49
they are supplementary angles
Answer:
y = - 10
Step-by-step explanation:
2x - 5y + 3 = 6x - 3y + 7
2(4) - 5y + 3 = 6(4) - 3y + 7
8 - 5y + 3 = 24 - 3y + 7
11 - 5y = 31 - 3y
11 - 11 - 5y = 31 - 11 - 3y
- 5y = 20 - 3y
- 5y + 3y = 20 - 3y + 3y
- 2y = 20
- 2y ÷ - 2 = 20 ÷ - 2
y = - 10
