Question

In AABC , C = 90°, if
find;
BC-a, Ac = b and
AB=c
1]c, when a=8cm and b=6cm
2)b,when c=13cm and a=5cm​

Answer 1

Answer:

Step-by-step explanation:

By pithagorous theorm hupotnuse^2= base^2+altitude^2

So

C^2=a^2+b^2

C=√8^2+6^2

C=√64+36

C=√100

=10

By Pythagoras's theorm

C^2=a^2+b^2

2). b^2=c^2-a^2

b=√13^2+5^2

b=√169-25

b=√144

b=12
