What is the surface are on this design

440 in 2

Step-by-step explanation:

440 in²

Step-by-step explanation:

5² = 25 in

8 × 5 × 4 = 160 in

(2 × 10 × 4) - 25 = 55 in

(10²) × 2 = 200 in

25 + 160 + 55 + 200 = 440 in²

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).
