Question

if there is a triangle of 40degree and 50 degree what will be the measure of third angle

Answer 1

third angle =180-50-40
=90 answer

Answer 2

let the third angle be x
according to question,
x + 40degree + 50degree = 180degree (by angle sum properties of triangle)
x + 90degree = 180degree
x = 180degree - 90degree
x = 90degree

The measure of third angle is 90degree
