Find the values of x and y. The diagram is not to scale.

51+x-5+y-6=180

x+y=180-51+5+6

X+y=140

Answer x=77 y=63

(those 2 lines with the arrows are perpendicular so their angles are the same 72° and (x-5)=77-5= 72°)

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
