Stonehenge is a British landmark made of huge stones arranged in a circular pattern that reflects
the movements of Earth and the moon. The diagram shows that the angle formed by the north/south
axis and the line aligned from the station stone to the northmost moonrise position measures 23.5°.
a. Find measure of arc BC.
b. Is arc ABC semicircle? Explain.

Find the formula for (f + g)(x).
f(x) = x² - 10x + 25 and g(x) = x² - 10x + 24
(f + g) (x) = [ 2 ]x²
