Answer 1

✤Hello mate!! good afternoon I have an answer to your question✤

✏Solution

First of all, value of third angle of ∆

Let third angle be y then,

30°+40°+y=180°   [∵ all ∡s of ∆ = 180°]

70°+y=180°

y=180°-70°

∴∡y=110°

Then we have,

∡y=∡O=110°

Again,

110°+x=180°  [ ∵ sum of co-interior ∡s is 180°]

x=180°-110°

∴ x= 70°
