Step-by-step explanation:

Answer 2

2x+3= 180°

5x= 180°

x= 180°/5

x= 36°

-----------

angle A = 2x = 2×36° = 72°

angle D = 3x = 3×36° = 108°(D)

-----------

4y+5y= 180°

9y=180°

y= 180°/9

y=20°

-----------

angle B = 4y = 4×20° = 80°

angle C = 5y = 5×20° = 100°

------------

Therefore,

angle A + angle B + angle C + angle D = 360°

So, 72°+80°+100°+108°= 360°
