Question

In the figure, <B is the right angle of ABC. write the following ratios: i) sinc ii) Cos C ii) tan c iv) Sin A​

Answer 1

here,

perpendicular (P)=AB

base(B)= BC

Hypotenuse (H)= AC

sinC= P/H= AB/AC

cosC= B/H = BC/AC

tanC= P/B = AB/BC

For sinA,

perpendicular (P)= BC

hypotenuse (H)= AC

therefore, sinA= P/H = BC/AC
