Evaluate when x = 2 and y = 5:
2 + (12 - 5x): 2g

Just substitute x = 2 and y = 5 into the equation wherever you see x and y.

2 + (12 - 5x) · 2y

2 + (12 - 5(2)) · 2(5)

2 + (2) · 10

4 · 10

40, is the answer which should be the first box.

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
