Question

Consider the right triangle given below. The length of side b to two decimal places is ____ pic attached

Answer 1

Answer:

$b=22.66\ units$

Step-by-step explanation:

we know that

In the right triangle ABC

$sin(65\°)=\frac{AC}{AB}$

in this problem we have

$AB=25\ units$

$AC=b\ units$

substitute and solve for b

$sin(65\°)=\frac{b}{25}$

$b=25*sin(65\°)=22.66\ units$

Answer 2

Using the sine rule, below is the solution to the problem given above:

Sine rule 
A = 90 - 25 = 65 
a/sin 65 = 25/sin 90 = 25 
a = 25 sin 65 
= 22.66 

The answer is 22.66. I hope this helps.
