Answer 1

Answer:

• The time period increases. It is because the centre of gravity of the system gets lowered in sitting position
• If BC= 12 cm then ar(ABC) is. ... right angled triangle in which angle B = 90° and angle C =2 × angle A we know, sum of all angles of any triangle = 180° ... AB = 12√3 cm
• ABC is a right-angled triangle in which angle B=90 degrees and angle C=2A. If BC= 12 cm then ar(triangle ABC) is ...
