Answer 1

*see the attachment below for the missing figure

Answer:

`sin B = (24)/(25)`

Explanation:

Given a right angled triangle, ∆ABC

AB = 25

BC = 7

AC = 24

<ACB = 90°

Required:

Value of Sin B

Solution:

Using trigonometric ratio formula,

`sin B = (opposite)/(hypotenuse)`

Opposite = AC = 24 (the side opposite to <B)

Hypotenuse = AB = 25 (the longest side facing the right angle)

`sin B = (24)/(25)`
