Question

many blankets did he have in the
15. Two angles of a triangle are in the ratio 1 : 2. If the
third angle is equal to the sum of the other two, find
the three angles of the triangle.​

Answer 1

Answer:

30,60,90

Step-by-step explanation:

let the ratio be x:2x +angle3=180 (angle sum property )

so(x+2x+(x+2x)=180)

3x+3x=180

6x=180

x=180/6

x=30

now angle 1 =x=30

angle 2 = 2x=2*30=60

angle 3 =angle 1 + angle 2=30+60=90
