Parallel = same slope
y = 3x + b
5 = 3(1) + b, b = 2
Solution: y = 3x + 2
since it has a diameter of 4, then its radius is half that, or 2.
Answer: x=3.5
Step-by-step explanation:
This is a 30-60-90 triangle. It is a special right triangle. You can tell by looking at the angle values. In this special triangle, the hypotenuse is 2x. x can be any number, and it is applied to each side of the triangle. Across from the 60° angle, the length is x√3. The length across from 30° is x.
Since we know the hypotenuse is 2x and the angle we are looking for, we can plug in to find x.
2x=7
x=7/2=3.5
