Question

one of the angles of a triangle is 75 degree . if the difference of the other two angles is 35 degree, then the largest angle of the triangle has a measure of:

Answer 1

Equations:


180=(75+x+y)
z-y=35
180=75+35+y
y=70.

Therefore angles are 70,75,35. Here 75 is biggest.

Ans=75deg

Answer 2

as we know that sum of all angles of triangle is 180 degree,so
EQUATION:
let one unknown angle be=x
that is why the other will be=(x+35)
that is why,
75+x+(x+35)=180
75+2x+35=180
2x=180-110
2x=70
x=70/2
x=35.
so,
first u
unknown angle=35
second unknown angle=70(35+x)
that is why the angles are,
75,70,35
so 75 is the largest angle of the triangle.
