Plz help me in this

Answer:
7.x=[tex]\sqrt{12^{2}- 11^{2} }[/tex]
x=[tex]\sqrt{23}[/tex] in
8.x=[tex]\sqrt{11^{2} -8^{2} }[/tex]
x=[tex]\sqrt{57}[/tex] yd
9.x=[tex]\sqrt{2^{2} +2^{2} }[/tex]
x=[tex]\sqrt{8}[/tex] m
10.x=[tex]\sqrt{9^{2} +6^{2} }[/tex]
x=[tex]\sqrt{117}[/tex] m
11.x=[tex]\sqrt{170-4^{2} }[/tex]
x=[tex]\sqrt{154}[/tex] mi
12.x=[tex]\sqrt{37+7^{2} }[/tex]
x=[tex]\sqrt{86}[/tex] yd
