Question

In a A ABC, ZB = 90°. If AB = 4cm and BC = 3cm, find the value of
sin A and tan c.​

Answer 1

Answer:

Step-by-step explanation:

In the triangle abc , ab =4cm and bc = 3cm

Then by pythagoras theorem

Ac^2 = bc square + ab square

Ac square =√25

That is =5

We got AC as 5 cm

Then sin A = opposite by hypotenuse

That is sin A= 3 / 5

Tan C = opposite by adjacent = 4/3
