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

the answer is the third / last answer

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
