Answer:

7) 8.94

8) 6.71

Step-by-step explanation:

for both questions, use pythagorean theorem

[tex]a^{2} + b^{2} = c^{2}[/tex]

Question 7:

[tex]4^{2} + 8^{2} = c^{2}[/tex]

16 + 64 = [tex]c^{2}[/tex]

80 =  [tex]c^{2}[/tex]

[tex]\sqrt{80} = \sqrt{c^{2}}[/tex]

c = 8.94

Question 8:

[tex]6^{2} + 3^{2} = c^{2}[/tex]

36 + 9 = [tex]c^{2}[/tex]

45 = [tex]c^{2}[/tex]

[tex]\sqrt{45} = \sqrt{c^{2} }[/tex]

c = 6.71
