Answer:
3rd = 96 and 4th = 144
Step-by-step explanation:
let the other angles be 2x and 3y respectively
we know that: A + B + C + D = 360
36+ 84 + 2x + 3x = 360
5x = 360 - 120
5x = 240
x = 48
2x = 2×48 = 96
3x = 3×48 = 144

Answer:
2 = 96 3 = 144
Step-by-step explanation:
36 + 84 + 2x + 3x = 360
2x + 3x = 36 + 84
5x = 120
5x = 360 - 120
5x = 240
x = 240/ 5
x = 48
2x = 2 x 48 = 96
3x = 3 x 48 = 144
