IN this question, it is given that
For all real numbers b and c such that the product of c and 3 is b.
That is

Solving for c by dividing both sides by 3

And we have to find an expression , that represents the sum of c and 3 in terms of b. And sum of c and 3 is

Substituting the value of c

So the correct option is the last option .
225/400 = 9/16
56 1/4% simplest form is 9/16
Answer:
x = 60°
Step-by-step explanation:
Use special triangles.
Starting with an equilateral triangle (all angles at 60°) with the side length of 2. Drop an altitude from one of the vertices to cut in half and make a right - triangle.
The hypotenuse length is 2. The base length, because it was cut in half, is 1. The height can be found with the Pythagorean theorem, which is √3.
The ratio for tangent is opposite over adjacent.
Since √3 = √3 / 1, the angle must be the one as marked in the picture.
Remember this triangle came from an equilateral triangle, so that angle is 60°. It was not cut in half, unlike the top angle which is 30°.
