Question

The measurecof two angles of triangle are 40 degrees and 60 degrees. Find measure of the third angle​

Answer 1

Answer:

80 degree as the measure of the three angles of triangles is 180 degree so 60 + 40 + 80 degree is equal to 180 degree and 180 degree equals to a triangle

Answer 2

let the third angel be x

40° +60 °+x=180

100+x=180

x=180-100

x=80°

the third angel is 80°
