Question

if two angle of triangle are of measure 60° and 75° then the measure of third angle is ​

Answer 1

Answer:

45° The sum of all angle of triangle is 180

so Adding 60+75+X=180

So X=45 which the third angle

Answer 2

Answer:

We know that sum of all angles of triangle is 180°

let the third angle be x

A/q

60°+75°+x=180°

135°+x=180°

x=180-135

x=45°
