Answer 1

BD and BE are tangents to the circle

Explanation:

Given

See attachment

Required

What does BD and BE represent?

From the attachment, we have:

`\angle BDA = 90^\circ`

`\angle BEA = 90^\circ`

`Radii = AD\ and\ AE`

The measure of angles between a tangent and the radius of a circle is always
`90^\circ\\`

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

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