Answer 1

x=65×2

because it is a circular angle

Answer 2

Answer:

130°

Step-by-step explanation:

By the theorem stated down,

"ANGLE SUBTENDED AT THE CENTRE IS DOUBLE THE ANGLE SUBTENDED BY IT AT ANY OTHER POINT ON THE CIRCLE."

STEP 1: As angle C is 65°, which is the angle subtended at other point on the circle from the central angle.

STEP 2: As it is half of the central angle, the central angle is twice of its subtended angle.

STEP 3: X= 65°*2

=130°
