In triangle ABC, a = 12, _ B= 25°, and
C= 45°. Find b.

The value of b is 5.4

Explanation:

Given that ABC is a triangle.

It is also given that , and

We need to find the value of b.

The value of b can be determined using the law of sine formula, which is given by

First, we shall find the angle of A.

Since, ABC is a triangle and all the angles in a triangle add up to 180°

Thus, we have,

Thus, the value of angle A is 110°

Let us substitute these values in the law of sine formula.

Hence, we get,

Simplifying, we get,

Multiplying both sides of the equation by 0.423, we get,

Simplifying, we get,

Dividing, we have,

Thus, the value of b is 5.4

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
