Answer:

Δ MNO ≅ ΔXYZ ⇒ proved down

Step-by-step explanation:

Cases of congruency

SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ

SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and including angle in the 2nd Δ

ASA ⇒ 2 angles and the side whose joining them in the 1st Δ ≅ 2 angles and the side whose joining them in the 2nd Δ

AAS ⇒ 2 angles and one side in the 1st Δ ≅ 2 angles and one side in the 2nd Δ

HL ⇒ hypotenuse and leg of the 1st right Δ ≅ hypotenuse and leg of the 2nd right Δ

Let us solve the question using the 4th rule above

∵ YZ = YO + OZ

∵ NO = NZ + ZO

∵ OZ = ZO ⇒ from the figure

∵ YO ≅ NZ ⇒ given

∴ YZ ≅ NO

In Δs MNO and XYZ

∵ ∠M ≅ ∠X ⇒ given

∵ ∠N ≅ ∠Y ⇒ given

∵ NO ≅ YZ ⇒ proved

→ By using the AAS postulate of congruency.

∴ Δ MNO ≅ ΔXYZ

The sum of solar energy can assumed as 'x', so it is easy to conclude that the sum of wind energy is '8x+56'. From the above assumption, we can easily get that 'x+8x+56=1037', to solve this equation and get tha

What kind of association is this? * Postitive Negative No association

solniwko [45]

It's negative correlation because the dots are dropping in value.

A positive correlation starts in the bottom left corner and rises to the top right. While a negative correlation starts at the top left corner, and drops in value. No correlation has dots randomly placed throughout the graph and a line can't be drawn to represent the correlation.
