Answer 2

Answer:

in a triangle you have given

one angle = 35 degree

other angle = 45 degree

third angle = ?

let third angle be y

by using angle sum property,

35 + 45 + y = 180

80 + y = 180

y = 180 - 80 = 100

let the angle corresponds to x be z

Angle z = angle Y ( vertically opposite angles)

so , z = y = 100 degree

the sum of corresponding angles is 180 degree

so , x + z = 180

x + 100 = 180 ( the value of z is 100 degree)

x = 180 - 100 = 80

so the value of x is 80 degree

hope it's help ✌✌
