Question

if you the two angle of a triangle are 50degree and 70degree then the measure third angle is
​

Answer 1

Answer:

120 degree

Step-by-step explanation:

If the two angles of a triangle are 50 degree and 70 degree, then the measure of third angle is

Answer 2

Answer:

the sum of all angles of a triangle is 180 degree;

let the third angle be x

therefore,

50degree + 70degree + x =180 degree

therefore =  120 degree + x =  180 degree

therefore , x  = 180 degree -  120 degree

therefore , x  =  60 degree.
