1. The value of a variable that makes an equation true.
2. In chemistry, a solution is a homogeneous mixture composed of only one phase
Answer:
Part 1) The value of b is 
Part 2) 
Step-by-step explanation:
Part 1)
Find the value of b
In the right triangle ABC
Let
b-------> the adjacent side to angle 22.6°
a -----> the opposite side to angle 22.6°
13 ----> the hypotenuse of the right triangle ABC
we have
The cosine of angle 22.6° is equal to divide the adjacent side to angle 22.6° by the hypotenuse

Solve for b
Multiply both sides by 13

Part 2) Which equation correctly uses the value of b to solve for a?
we know that
In the right triangle ABC
The tangent of angle 22.6° is equal to divide the opposite side to angle 22.6° by the adjacent side to angle 22.6°
so

we have

substitute
