Easy 8th-grade math question ​

-16

Step-by-step explanation:

The Square root of 256 is 16 and since there is a negative sign in front hat makes it negative 16, although root 256 is technically answered with 16, and -16...when there is a minus or negative sign in front...it usually means they would prefer the answer negative.  

the answer is 15.0 for your answer

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).
