Answer: y=0,5x²-x-1,5.
Step-by-step explanation:
We summarize (1) and (3):
Substitute b=-1 into (2):
From (5) subtract (4):
Substitute a=0,5 into (4):
Hense:
y=0,5x²-x-1,5.
Subtract 60 on both sides to get -40.
You are left with 40x=-40
Divide both sides by 40 to leave x by itself.
You get x=-1.

Applying the properties of a kite, m∠WZY = 128°.
<h3>Properties of a Kite</h3>
- The diagonals of a kite bisect each other perpendicularly.
- The main diagonal bisects the opposite angles.
Given:
m∠ZWY=41∘
m∠XYW=11∘
m∠WZY = (180 - 90 - 41) + (180 - 90 - 11)
m∠WZY = 49 + 79
m∠WZY = 128°
Therefore, applying the properties of a kite, m∠WZY = 128°.
