Step-by-step explanation:
<u>Question 1</u>
<u>The missing angles</u>
Both the unknown angles have the same value as the other two angles in the triangles are the same ∠(missing) = 180 - (72 x 2) ∠(missing) = 180 - 144 ∠(missing) = 36°
⇒ The sides are <u>equal</u>
⇒ Angles are <u>not 90°</u>
⇒ It is a <u>rhombus </u>
<u>
<u>Question 2</u>
The <u>diagonals</u> of the shape <u>bisect other</u> (Statement 1 ) NY = NW (given) XN = NZ (given) ∠XNY = ∠WXZ (vertically opposite angles) ΔXNY ≅ ΔWXZ (SAS) They form <u>two congruent triangles</u> (Statement 2 ) From these two statements, it is evident the figure is a <u>parallelogram </u>

Hi
We know that, 1 litre = 1000 ml
Then, 2 litres = 2000 ml
Hence, the required ratio of 1000 ml to 2000 ml be
= 1000 : 2000
= 1 : 2
The equation should have been written as 1.25x+1.49y=100.
The error made in the first equation was that Barbara did not include a variable next to the term 1.49. Since the ice tea is sold for $1.49 per bottle, a variable should be included to represent however many bottles of iced tea she sold.
