Describe the error in the work shown below. Find an expression equivalent to 18 + 30 Factors of 18: 1,2,3,6,9,18

factors of 30: 1,2,3,5,6,10,15,30

18 + 30=6(3+10)

69

step-by-step explanation:

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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).

m=-16
