Question

In a triangle, the sum of the two angles is equal
to the third. If the difference between them is 50º,
determine the angles.​

Answer 1

Step-by-step explanation:

let the angles of the triangles be x,y,z

according to the question

x+y=z........1

x-y=50° .......2

we know that

x+y+z= 180°

from equation1

z+z=180°

2z= 180°

z= 90°

so, x+y=90.....3

from equation 2 and 3

x-y=50°

x+y= 90

_______________

2x= 140

x=70

now from equation2

70-y=50

y=20
