4 Ways to Find the Height of a Triangle - wikiHow
Web30 de jun. de 2024 · But since the large triangle has the same height as the white triangle, but three times its base, we have Δ large = 3 Δ white. So. 2 h 2 + 36 = h 2 + 1 h 2 + 9. Squaring both sides and simplifying gives. h 4 + 10 h 2 + 9 = 4 h 2 + 144. ⇒ ( h 2 + 15) ( h 2 − 9) = 0. So h = 3, and the shaded area is 6. Share.
