Question

In figure , angle X + angle Y. =?​

Answer 1

Step-by-step explanation:

angle Y = 180⁰ - 120⁰ = 60⁰

P + Q + R = 180⁰

X + 40⁰ + 60⁰ = 180⁰

X = 180⁰ - 100⁰

X = 80⁰

angle X + angle Y

= 80⁰ + 60⁰

= 140⁰

Answer 2

y+120=180

y=180-120

y=60

sum of the angles of triangle is 180

40+x+y=180

40+x+60=180

x=180-100

x=80

(x=80,y=60)
