- Answer: Using the Pythagorean Theorem
Step-by-step explanation:
The Pythagorean theorem states that a^2+b^2=c^2.
For 51, Here would be the step by step (you would do the same thing for 52, follow the formula)
[tex]6^{2} + 3^{2} =c^{2} \\36+9= c^{2} \\45=c^{2} \\\sqrt{45} =\sqrt{c^{2} } \\c= 6.7[/tex]
For 53 (and 54), c is already provided. Instead of adding, do this (again, follow the formula):
[tex]a^{2} + 3^{2} = 7^{2} \\a^{2} + 9 = 49\\a^{2} + 9 = 49\\a^{2}= 40\\\sqrt{a^{2}} =\sqrt{40} \\a= 6.32[/tex]
I hoped this had helped.
