please solve it .............................​

Answer 1

Step-by-step explanation:

From figure (ii),

In ∆XYZ , YX is extended,

<a = <3 + <4 -----(i)

/* Exterior angle at X = sum of interior opposite angles */

Similarly ,

<b = <2+<5 -----(ii)

Now,

From (iii) figure ,

<1+ <a+ <b = 180°

/* Angle sum property */

=> <1+ (<3+<4)+(<2+<5)=180°

=> <1+<2+<3+<4+<5 = 180°

Hence , proved .
