Subject: Finding the height of a triangle Hey, I'm trying to find the height of a triangle but i only know the base and one of the sides as well as the angle between those two sides...but how can i find the height? |
Hi Shanelle,
In the diagram h is the height so triangle PQS is a right triangle. Thus
sin(t) = h/a
Hence if you know the angle t and the length a you can find h, h = a sin(t).
