Question

If anyone could help message me I have 3 questions to ask. Because I don’t understand this

Answer 1

Answer:

Step-by-step explanation:

See in the figure cord EC angle is 180 degree as it's straight and BD the radius bisects it means it's divides the cord in to two equal parts or amgles

So we know that cord EC is 180 degree and when it will be divided I to two equal parts each angle will be 90 degree.

So angle BAE is 90 degree

And angle ABE is given 58 degree

Now we know that BAE is a triangle formed in the figure and sum the the three angles of a triangle is 180 degree

So angle BAE + angle ABE + angle BEA = 180 degree( angle sum property)

So 90 degree+58 degree+ angle BEA =180 degree

=148+ angle BEA =180 degree

So, angle BEA =180-148

angle BEA=32 degree
