There are markings given in the diagram.

(Angle) ∠A and ∠D are =

(Side) AC and DB are =

(Side) In a trapezium, the opposite sides are equivalent, meaning AB and DC are =

So you got side, angle, and another side.

You can form the SAS (Side-Angle-Side) similarity theorem.

You can also use the reasons above to make a Statement-Proof table

What point on the parabola is closest to the point

Thepotemich [5.8K]

Answer:

Suppose the closest point is at p=(x0,y0), and set q=(−2,−3). Then the tangent to the parabola at p is perpendicular to ℓ, the line through p,q. and we end up numerically computing the roots from here.

Workout the length of AB. Give your answers to 3 significant figures.

german

Answer:

AB ≈ 6.71

Step-by-step explanation:

Calculate the length using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = A (- 1, 6) and (x₂, y₂ ) = B (5, 3)

AB = $\sqrt{(5-(-1))^2+(3-6)^2}$

= $\sqrt{(5+1)^2+(-3)^2}$

= $\sqrt{6^2+9}$

= $\sqrt{36+9}$

= $\sqrt{45}$

≈ 6.71 ( to 3 significant figures )
