Answer 2

Answer:

angle 1= angle 3 = 75

angle 2= angle 4 = 105

Step-by-step explanation:

since angle 1 + angle 2 = 180

let angle 1 be 5x

and angle 2 be 7x

therefore

5x+7x=180

x=15

thus angle 1 = 75

angle 2 = 105

now we know angle 1 = angle 3 vertical opposite angle

similarly angle 2= angle 4
