Question

What is the length of line segment ABin the triangle shown below?
B=8 inches
A=17 inches

Answer 1

√Answer: 15inches

Explanation:

For this triangle,we can use Pythagoras' theorem

The state is that : a²+b²=c²

In this figure,notice that a shorter side needs to be found,so after writing the Pythagoras formula in the usual way,the formula has to be rearranged to make x² the subject

a²+b²=c²

8²+x²=17²

64+x²=289

x² = 289- 64

x² = 225

x = √225 =15inches
