Question

One angle of a triangle is 30° and the other two angle are equal what will be the measure of each of these angle

Answer 1

Let the two unknown angles be x (as they both are equal to one another)

30+x=180 (angle sum property )

X=180-30

×=150

Answer 2

one angle is 30 degree

let the missing angles be 2x,then

30+2x=180

2x=180-30

x=75 degree Ans....................
