Answer:
use this formula and answer A=L*H
Y=kx^2 (k being a constant)
72=k (3^2)
k=8
y=8x^2
Answer:
The lengths of all sides of the triangle will be 21 cm, 21 cm, and 21 cm
Step-by-step explanation:
Given that the perimeter of the triangle = 63 cm
And the length of one side = 21 cm
and one of the medians is perpendicular to one of its angle bisectors
Since triangle has 3 sides,
Median = 63 ÷ 3 = 21
Therefore each side length = 21 cm
There are 146 - 84 = 62 girls
ratio is 84:62
simplifies to 42:31
