10) a = 9 cm, b = 13 cm

Find c a^2+b^2=c^2

a=9 b=13

Find c.

Well you first substitute a and b for the real numbers ^^

9 to the 2nd power or 9 squared.

13 to the 2nd power or 13 squared

Im other words

Not 13 multiplyed by 2 or 9 multiplyed by 2!

Squared means 13 multiplyed by itself.

13•13 = 169

Same for 9.

9•9 = 81

Therefore,

81 + 169 = c

Figure that out and you'll get your answer!

Step-by-step explanation:

First you write out the equation 9^2+13^2=C^2

81+169=C^2

250=C^2

√250=C

C=5√10
