Question

If one angel of a triangle is 80° and the other two angles are in the ratio 2:3,find the angles

Answer 1

Answer:

***********************HEY DEAR************************

HERE IS YOUR ANSWER.......

IN A TRIANGLE ,

SUM OF ANGLES = 180 DEGREE

LET ONE ANGLE = 2X

OTHER ANGLE = 3X

BECAUSE IN QUESTION ITS GIVEN THAT THEY ARE IN RATIO 2:3 SO WE TAKE LIKE THAT

NOW,

2X +3X +80  = 180

 5X = 100

  X = 20

SO ANGLES ARE : 80, 40, 60 DEGREE

THESE ANGLES ARE OBTAINED BY PUTTING VALUE OF X..

Answer 2

are of triangle = 180
2x + 3x + 80 = 180
5x = 180 - 80
5x = 100
x = 100÷5
x= 20
1st angle = 2x = 2 × 20 = 40 degree.
2nd angle = 3x = 3× 20 = 60 degree .
I HOPE THIS ANSWER IS HELP YOU. .
