Question

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

Answer 1

Answer:

Step-by-step explanation:

Let the angles be x, y and x

Given,

x+y=80

x-y=20

By using elimination method we get

(x+y=80)

-(x-y=20)

2y=60

y=60/2=30

X=50

Z=100 (by applying angle sum property)
