Answer 1

Answer:

130 degree

Step-by-step explanation:

the summation of these 4 angles will give a total of 360 degree.. you have to substract 230 from 360 which will be equal to 130 degree

Answer 2

Answer:

1 + 2 + 3 = 230⁰ (Given) — i

1 + 2 = 180⁰ (linear pair)

put in i

180⁰+ 3 = 230⁰

3 = 230⁰-180⁰

angle 3 = 50⁰

angle 3 + angle 4 = 180⁰ (linear pair)

50⁰ + angle 4 = 180⁰

angle 4 = 180⁰ - 50⁰

angle 4 = 130⁰
