A∠a and ∠ b ∠b are complementary angles. if m ∠ a = ( 2 x − 23 ) ∘ ∠a=(2x−23) ∘ and m ∠ b = ( x + 20 ) ∘ ∠b=(x+20) ∘ , then find the measure of ∠ a ∠a.

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.
