What do the measures of angles BDA and BEA and the fact that AD and AE are radii of circle A tell us about BD and BE



Font Sizes

Answers

Answer:

BD and BE are tangents to the circle

Step-by-step explanation:

Given

See attachment

Required

What does BD and BE represent?

From the attachment, we have:

[tex]\angle BDA = 90^\circ[/tex]

[tex]\angle BEA = 90^\circ[/tex]

[tex]Radii = AD\ and\ AE[/tex]

The measure of angles between a tangent and the radius of a circle is always [tex]90^\circ\\[/tex]

So, because [tex]\angle BDA = 90^\circ[/tex] and AD is a radius, then BD is a tangent to circle.

Similarly,; [tex]\angle BEA = 90^\circ[/tex] and AE being a radius implies that BE is a tangent to circle.

As we all know, Pinocchio’s nose grows when he tells a lie.

So if he said “my nose will grow now” – if his nose does grow that would mean he wasn’t lying, but if he wasn’t lying, his nose wouldn’t grow.

But then his statement would be a lie… so his nose would grow.. but then the statement wouldn’t be a lie… so his nose wouldn’t grow… but yeah, you get the idea..

Basically, his nose would have to grow to make Pinocchio’s statement not a lie, but then it can’t grow otherwise the statement would not be a lie.
