20 pts examine the diagram. transversal n intersects lines l and m to form 8 angles. the angles formed with line l, clockwise from top left are 63 degrees, (15 x minus 3) degrees, blank, blank. the angles formed with line m, clockwise from top left are (8 x + 7) degrees, blank, 1, blank. what is the m∠1?

a)21°

b)42°

c)71°

d)82°

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

false

inverse variation is not exponential
