Hi
You should put into them.I mean
1-This is 2 part.First, you should put f(-1) then you should put what you found.
Solve is:f(-1)=3(-1)-2(-1)^2 so -3-2=-5 then put in other one:if f(-5):-15-50=-65
Is it correct?

Please help<br> maths geometry

Answer:

D₁ = 68°

Step-by-step explanation:

If AB = BE then ΔABE is an isosceles triangle, therefore A₁ = E₁.

If A₁ = 28° then E₁ = 28°.

<u>Opposite sides</u> of a parallelogram are <u>parallel</u>.

Using the Alternate Interior Angles Theorem:

A₂ = E₁ = 28°

Therefore, A = A₁ + A₂ = 28° + 28° = 56°

<u>Opposite angles</u> in a parallelogram are <u>equal</u>.

Therefore, C = A = 56°.

<u>Opposite sides</u> of a parallelogram are <u>equal in length</u>, so AB = CD.

If AB = DE = CD then ΔCDE is an isosceles triangle.

Therefore, C = E₃ = 56°.

Interior angles of a triangle sum to 180°.

⇒ D₁ + C + E₃ = 180°

⇒ D₁ + 56° + 56° = 180°

⇒ D₁ + 112° = 180°

⇒ D₁ = 180° - 112°

⇒ D₁ = 68°
