Answer:7.62, if not just 7.6 orr 58 read explanation lol
Step-by-step explanation:
i did the math and i doubled checked on a calculator :P,
cause you use the formula c= [tex]\sqrt{a^2+ b^2}[/tex] and in this case a^2 and b^2 is 3^2 and 7^2 and then you solve so its 9 and 49 and then add them which is 58 and then you find the square root of 58 which is 7.6 or in your case you put 58 under the square root
