Given the triangles in the drawing
What is the length of the side DB?
In this question, we will have to use the Pythagorean theorem twice.
A²+B²=C²
Let's start by finding side CB:
6²+CB²=(2√11)²
36+CB²=4*11
CB²=44-36
CB²=8
CB=√8
We will use the exact same way to find side DB:
2²+DB²=(√8)²
4+CB²=8
CB²=8-4
CB²=4
CB=√4=2
2 cm
Consider a right-angled triangle, AB = 8 cm and AC = 6 cm.
Calculate the length of side BC.
