| A triangle with sides 15 and 5 has heights to these sides. the height drawn to the first side is 1. What is the height drawn to the second side?
The area of the triangle is:
S = (a × h) / 2, where a is the length of the side of the triangle, h is the length of the height of the triangle dropped to side a.
Let us denote the required height length as x.
We get:
S = (15 × 1) / 2.
Also S = (5 × x) / 2.
We equate the obtained expressions and solve the equation:
(15 × 1) / 2 = (5 × x) / 2;
15 = 5 × x;
x = 3.
Answer: The length of the height drawn to the second side is 3.
