please answer this question fast with xplanation there are 2 questions

Answer 1

Answer:

18) x = 50 degrees and y = 50 degrees

Step-by-step explanation:

x = 50 degrees ( vertically opposite angles are equal)

180 degrees =130 degree + y(linear pair axiom)

y = 180 degrees - 130 degrees

y = 50 degrees

19) let the ratios be 2x and 3x

the exterior angle given is 130 degree

apply linear pair axiom

180 degree = 130 degree + y

y = 180 -130

y = 50 degree

angle sum property of triangle states that

angle (1) + angle (2) + angle (3) = 180 degree

50 +2x+3x=180 degree

5x = 180 - 50

5x = 130

x = 130 divided by 5

x = 26 degree

2x = 2* 26 = 52 degree

3x = 3* 26 = 78 degree
