Answer 1

$\huge{\boxed{ \boxed{\mathbb{ \red{ANSWER}}}}}$

(C)

(i) Angle ACB = (180 - 50 - 90)

= 40°

So, AngleCAE = 40° (Alternate angle.)

As Ang.BAE = 40+50.. i.e 90°.

Therefore, BE is also the diameter.

ii) Ang. EDC = 110°

iii) Ang. BEC = 40°

Answer 2

Answer:

i) 40 degrees - Angle EAC will equal 90 and because it is parallel to line BC, ACB will also equal 90-50=40.

ii) EDC = 180 -40 =140 degrees because opposite angles of a quadrilateral sum up to 180 degrees.

iii) AEC = ABC = (180 - (50 + 40)) = 90. Therefore 90/2 = 45 = BEC because opposite angles form 180 and sum of angles of triangle are 180.
