Answer:
167º
Step-by-step explanation:
The interior angles in an n-gon add up to 180(n-2). So, the interior angles in a 28-gon add up to 180(28-2)=180(26)=4680. To find out the measure of one angle divide 4680 by 29. 4680/28 is about 167.
Answer:
x ∈ {-0.465, 1.014}
Step-by-step explanation:
The equation can be cast in the form f(x) = 0, and solved easily using a graphing calculator. That shows x ≈ -0.465 and x ≈ 1.014. The same calculator can iterate the roots to full calculator precision.

Answer:
A
Step-by-step explanation:
Subtract 1 from both sides and divide by 2. This will leave you with x=-2 which is the simplified form of the equation.
