Question

if one angle of a triangle is 80 degree and other two angles are in the ratio 2 ratio 3 find the angles​

Answer 1

Answer:

40:60

Step-by-step explanation:

the total angle in a triangle is 180 the given angle is 80 subtract 80 from 180 we get 100 divide it with 5 because total parts of ratio is 5 then we get 20 multiply it with 2:3 then we get 40:60

Answer 2

Step-by-step explanation:

given

the two ratio of Angles 2:3

let the angles of triangle be X

A. T. Q.

sum of angle of triangle=180

=>2x+3x+80=180

=>5x=180-80

=>5x=100

=>X=20

hence the two angle of triangle are

2x=2*20=40

3x=3*20=60

for verification

sum of the value of angle

80+40+60

180 proved
