Triangle ABC is similar to Triangle DEF. segment AB/ segment AC = segment DF/ segment EF is a proportion: < true or false?>

also written as:
ĀB/ĀC = DF/ĒF

If Δ ABC is congruent to Δ DEF, then its corresponding parts must be congruent.

1. segment AB ≅ segment DE [first two letters]  

2. segment BC ≅ segment EF  [last two letters]

3. segment AC ≅ segment DF[first and last letters]

∠A ≅ ∠D [first letter]

∠B ≅ ∠E [mid letter]

∠C ≅ ∠F [last letter]

So from the given options, the only statement that is not true is ∠C ≅ ∠E.

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

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).
