Answer:
c = 1
Step-by-step explanation:
Given
x² + 2x + c
To complete the square
add ( half the coefficient of the x- term )² to x² + 2x
x² + 2(1)x + 1
= (x + 1)²
Thus
x² + 2x + 1 = (x + 1)² ← a perfect square
with c = 1

Hi there!
In order to solve for x, we'll need to use a trigonometry ratio. In this case, we'll use tangent, which is opposite over adjacent.
Here is our equation:
tan(37)/1 = x/2.1
Cross-Multiply:
x = tan(37) * 2.1
Solve:
x = 1.8 (rounded to the nearest tenth)
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
