BH – height,
P ABC = 36 centimeters,
P ABH = 18 centimeters;
R BHC = 24 centimeters.
Find the length of the height BH -?
Consider a triangle ABC.
P ABC = P ABH + P BHC – 2 * BH;
2 * BH = P ABH + P BHC – P ABC;
2 * BH = 18 + 24 – 36;
2 * BH = 42 – 36;
2 * BH = 6 (in order to find an unknown factor, you need to divide the product by a known factor);
BH = 6: 2;
BH = 3 centimeters.
Answer: 3 centimeters.
