Yogita Ingle 4 years, 9 months ago

Let us consider two congruent circles (circles of same radius) with centers as O and O

In ΔAOB and ΔCO'D,

AOB = CO'D (Given)

OA = O'C (Radii of congruent circles)

OB = O'D (Radii of congruent circles)

ΔAOB ΔCO'D (SAS congruence rule)

AB = CD (By CPCT)

Hence, if chords of congruent circles subtend equal angles at their centers, then the chords are equal.

Let angle be x x+35=90 x=90-35 x= 55°

Yogita Ingle 4 years, 9 months ago

When two angles are added together and they total 90 degrees, they are said to be complementary angles.

Let the angle be x

then x + 35° =90°

x = 90° - 35°

x = 55°
