Question

Two angles of a triangle are of measures 75°and 35° find the measure of the third angle .

Answer 1

let the required angle be x
as we know that sum of angles in a triangle =180degree
then
75+35+x=180
110 +x=180
x=180-110=70 degree

Answer 2

Hey friend:)

Let the three angles be x,y,and z

X+y+z=180°(angle sum property of a triangle)

75°+35°+z=180°

110°+z=180°

z=180°-110°

Z=70°

The third angle is 70°
