Step-by-step explanation:

The sum of all the interior angles of a pentagon is 540°.

Therefore,

a+(a+10)+(a+20)+(a+30)+(a+40) = 540°

a+a+10+a+20+a+30+a+40 = 540°

5a+100° = 540°

5a = 540°- 100°

5a = 440°

a = 440°/5

a = 88°

The largest angle will be -

(a + 40°) = 88° + 40°

= 128°.

Hope it helps.....
