Answer 1

Step-by-step explanation:

Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant.

Answer 2

Answer:

Answer:14 min 25 sec

perimeter of park=2(l+b)=2(100+80)=2*180=360 m

distance of 1 round =360 metres

distance of 6 rounds=360*6=2160 metres

speed of mridul=9 kmph=9*1000/3600=2.5 m/s

Speed =distance/time

→time=dist./speed=2160/2.5=865 sec=14 min 25 sec
