Step-by-step explanation:

A (8+10)*2 C (10*2)+(8*2)

Step-by-step explanation:

I'm not sure if this is a multiple choice question but if it is both of those make 36 which is the same as the expression you are comparing it to. All you need to do really is plug each of these into a calculator and see which ones equal the same as (10+8)*2

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).

hi how are you doing today? if you ever need just tell me
