Question

in the figure, if x°,y°,z° are the exterior angle of triangle ABC then find the x°+y°+z°.​

Answer 1

Step-by-step explanation:

we

Know that

sum of (interis + exterios) angle

of a triangle = 180° as they form

a straight line.

so,

LBAC = 180°-xz

LABC = 180 - x

LACB = 180-y

sum of angles in a triangle = 180°.

BAC + ABC # (ACB = 180°

180-2 + 180-x+ 180-y= 180

360° = 1+y+z (or) =

てty+Z = 360°

Answer 2

Answer:

x+z+y=2×total angle i. e. 180°

So, x+y+z=360°
