What is the measure of the missing angle?

answer:

60 degrees

step-by-step explanation:

35 + 25 + x = 180

180-60=120

180 = 120 + x

x = 60

60 + 60 + x = 180

x=60

(the total of all angles is equal to 180)

: )

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

i believe that the slope of the line is -5
