Question

the sum of two angles of a triangle is 80 degree and their difference is 20 degree find all the angles of the triangle​

Answer 1

50,30, loo are the answers

Answer 2

Answer:

angles are 30,50 and 100

Step-by-step explanation:

let the angles be x and y

so,x+y=80

x-y=20

then apply elemination method

on adding

x + y =80

x - y = 20

then y is cancel and

2x = 100

x = 100/2

x = 50

now, put the value of x in x+y=80

50 + y =80

y = 80 - 50

y = 30

then remaining angle =180 - ( 50+30)

180 -80 =100
