Question

Measure of two angles of a triangle are 60 and 70 degree. Measure of the third angle is​

Answer 1

Answer:

angle 1+angle2+angle 3=180°

60°+70°+angle 3=180°

180-(60+70)=angle3

:. angle 3 = 50° after equating

Answer 2

Answer:

sum of angles of a triangle is 180 degree

let x be the third angle

therefore, 60+70+x=180

130+x = 180

x = 180-130 = 50

x = 50°
