Step-by-step explanation:
<h2>Area of scalene triangle:</h2>
Here, a, b and c are the sides of the triangle. s is the semi perimeter.
a = 13
b = 14
c = 15
s -a = 21 - 13 = 8
s -b = 21 - 14 = 7
s - c = 21 - 15 = 6
X directly varies with y which means as x increases, y also increases. In this case, we represent a constant of proportionality of k.
Applying laws of <span> proportionality,
x =k y
48 = k* 16
k = 3
when y is 5
x = k y
x = 3* 5
x = 15</span>
