The exterior angles of a triangle are 3y, 4y and 5y find the smallest interior angle of the triangle

I don't know maybe it this way but am sure the answer is 15

Step-by-step explanation:

3y+4y+5y=180(sum of angle in a triangle)

12y=180

divide both side by 12

ur Y will be

y=15

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
