Question

can anyone help me with my homework

Answer 1

Hiii dude....

Here

a=12cm

b=5cm

Find x=?

Let right angle ABC=90°

Here, AB=b BC=a AC=x

By pythagoras theorem...

AC²=AB²+BC²

=5²+12²

=25+144

=169

AC²=169............ Taking square root of both side

AC=√169

AC=13

Therefore, x=13

Hope this will help you.......

Answer 2

Step-by-step explanation:

a = 12

b = 5

12*2 + 5*2 = x*2

144 + 25 = x*2

169 = x*2

x = 13
