We have been given that ∠Q is an acute angle such that
. We are asked to find the measure of angle Q to nearest tenth of a degree.
We will use arctan to solve for measure of angle Q as:

Now we will use calculator to solve for Q as:

Upon rounding to nearest tenth of degree, we will get:

Therefore, measure of angle Q is approximately 2.3 degrees.
Answer:
The price of the piano is $311.69
3/k+3=8/k-2
butterfly (multiply 8 and k+3) and (multiply 3 and k-2) and set them = to eachother
8 (k+3)=3 (k-2)
distribute
8k+24=3k-6
-3k both sides
5k+24=-6
-24 both sides
5k=-30
÷5 both sides
k=-6
