Answer:
Number 3: The answer is 31.8
Number 4: I got about 9.49ft as the answer.
Step-by-step explanation:
a^2 + b^2 = c^2
so 13^2 = 169
29^2 = 841
841+169 = 1010
the square root of 1010 is about 31.8
I did the exact same thing for the second one just using different numbers, 3 and 9 (as shown in the picture).
