Answer:
4a+7 over 2 = b.
Step-by-step explanation:
First add 7 to both sides to get 2b by its self so you will have 4a+7=2b. Then, to get B by itself, divided both sides of the equation by to, so you will have 4a+7 (over 2) = B.
By <em>trigonometric</em> functions we find that the measure of angle A is approximately 0.12π radians.
