Find the missing length PLEASE HELP NEED IT ASAP

Answer:
c = [tex]\sqrt{58}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
c² = 7² + 3² = 49 + 9 = 58 ( take the square root of both sides )
c = [tex]\sqrt{58}[/tex]
Answer:
Step-by-step explanation:
According to Pythagoras Theorem:
[tex] {7}^{2} + {3}^{2} = {c}^{2} [/tex]
Hence,
[tex] = > {c}^{2} = {7}^{2} + {3}^{2} [/tex]
[tex] = > {c}^{2} = 49 + 9[/tex]
[tex] = > {c}^{2} = 58[/tex]
[tex] = > c = \sqrt{58} [/tex]
So,
[tex]c = \sqrt{58} [/tex]
Is the answer.
