Step-by-step explanation:
The hypotenuse is the distance from home to second, or side x.
The legs are from home to first and from first to second.
answer:
a = 15
b = 84
c = 81
steps
a+b+c=180
b=3a+39
c=a+66
a+3a+39+a+66=180
5a + 105 = 180
5a = 75
a = 15
b=3a+39
b=3(15)+39
b=45+39
b=84
c=15+66
c=81

Answer:
Step-by-step explanation:
Total no. of children = 366
let the number of boys be x
and the no. of girls be x + 28
According to the question,
x + x + 28 = 366
2x + 28 = 366
2x = 366 - 28
2x = 338
x = 338 / 2
x = 169
So the no. of boys = x = 169
and the no. of girls = x + 28 = 169 + 28 = 197
( you can also recheck it by adding the no. of boys and the no. of girls
that is, 169 + 197 = 366 which equal to the total no. of children )
