Question

FOR EACH OF THE FOLLOWING TRIANGLES FIND THE VALUE OF X AND Y

​

Answer 1

Answer:

THERE IS ONLY ONE.

Step-by-step explanation:

your answer :

let us take A B C as sides of triangle

angle A + angleB + angle C =180⁰

(triangle property)

80⁰ + 40⁰ + C(x) =180⁰

120⁰+C =180⁰

180⁰-120⁰=C

C = 60⁰

therefore x = 60

ii)40⁰+ y = 180⁰

y = 140⁰

Answer 2

Step-by-step explanation:

We know that,

sum of any triangle is 180

so, 80`+40`+ x = 180

120 + x = 180

x= 180-120 =60

=> x =60`

now,

from liner pair

40 + y = 180` (liner pair)

y = 180-40

y= 140`

hence, X=60` and Y =140` .
