Question

16. One of the angles of a triangle is 65°. If the difference of the other two angles is
25°, then they are :
answer​

Answer 1

one angle is 65°

sum of other two angles= 180-65=115°

let the other angles be x and y

therefore x+y = 115

the difference between x and y is 25°

so; x +(x+25) = 115

2x+25. = 115

2x. = 90

x. = 45°

therefore y = 45+25 = 70°

Answer 2

1st angle =65

let 2nd angle be =x

3rd angle=x-25

180=65+x+x-25=180(angle sum property)

65+2x=180+25

65+2x=205

2x=205-65=140

x=70

x-25=70-25=45

hope this helps!!!
