A traveler exchanged 138 U. S. dollars for 100 Euros. Which of the following equations shows the equivalent for this exchange? A:1.38 = 19/50 = 0.38%
B:1.38 = 69/500 = 0.138%
C:1.38 = 69/5 = 0.138%
D:1.38 = 69/50 = 138%

step-by-step explanation:

it's the only multiple of both and the least

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).

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
