Answer: They didn't solve the problem all the way, you need to find the square root of 674. The final answer is 25.96
Step-by-step explanation:
[tex]a^{2}[/tex] + [tex]b^{2}[/tex]= [tex]c^{2}[/tex]
[tex]7^{2}[/tex] + [tex]25^{2}[/tex] = 674
[tex]\sqrt{674}[/tex] = 25.96
Answer:
= sq rt 576
25^2 - 7^2 = c^2
25^2 - 7^2 =c^2
sq rt 576 = c^2
Answer is sq rt 576 it is not sq rt 674 = c^2 as we are given the hypotenuse to square and so we subtract b^2 from it to give a^2
we can use hypotenuse and any right angle side b^2 to find a^2
c^2 - b^2 = a^2 is formula
25^2 - 7^2 = a^2
25^2 - 7^2 =a^2
sq rt 576 = a^2
