Question

The angels of a triangle are arranged in ascending order of magnitude . if the difference between two consecutive number is 10,find the three angles

Answer 1

let one of the angles be x

then according to question,

x+x-10+x-20=180

3x-30=180

3x=210

x=70

x-10=60

x-20=50

therefore the three angles are 70 degrees, 60 degrees and 50 degrees
