Answer:
Length of BC = 12 inch
Step-by-step explanation:
Given:
ΔABC is a right angle triangle
Length of AB = 9 inch
Length of AC = 15 inch
Find;
Length of BC
Computation:
Using Pythagoreans theorem;
Hypotenues² = parpendicular² + Base²
Step 1 :
AC² = AB² + BC²
Step 2 :
15² = 9² + BC²
Step 3 :
225 = 81 + BC²
Step 4 :
225 - 81 = BC²
Step 5 :
BC² = 144
Step 6 :
BC = √144
Step 7 :
BC = 12 inch
Length of BC = 12 inch
