Answer:
∠1 + ∠2 + ∠3 = 180°
Step-by-step explanation:
Given : AB II XC
To Show : ∠1 + ∠2 + ∠3 = 180°
Proof: Here, given that AB is parallel to the line XC
⇒ ∠4 = ∠2 (Pair of Alternate angles as AB II XC) ......... (1)
and ∠5 = ∠3 (Pair of Alternate angles as AB II XC) ........... (2)
Now, ∠1 + ∠4 + ∠5 = 180° ( Straight Angle)
But, from above (1) and (2)
∠1 + ∠2 + ∠3 = 180° ( as ∠4 = ∠2, ∠5 = ∠3)
Hence, ∠1 + ∠2 + ∠3 = 180°
Hence Proved.
the correct answer is negative
Answer:
677
Step-by-step explanation:
785-27= 758
27*3= 81
758- 81= 677
I hope this helps!!!!
In the figure you can say ∠1 + ∠4 = 180° because both together make a line so you can say : 63° + ∠4 = 180° ⇒ ∠4 = 180° - 63 ° = 117 ° so the answer is :
∠4 = 117° :)))

Answer:
each barrel has a capacity of 78,75 liters
Step-by-step explanation:
since the sold 8 barrels and assuming that each have the same capacity and are sold to the same price, the total amount he earned is
total earnings = number of barrels * number of liters/ barrel * earnings/liter
R$1,260,00 = 8 barrels * number of liters/ barrel * ( R$9,00- $7,00) /liter
number of liters/ barrel = R$1,260,00/(8 barrels*R$2,00 /liter ) = 78,75 liters/barrel
therefore each barrel has a capacity of 78,75 liters
