Question

Help me please!!!!!!!

Answer 1

1st one: c^2=5\sqrt{2}^2+5\sqrt{2}^2=50+50=100, so c=10
2nd one: x^2=8^2/2=32, so x=4\sqrt{2}
3rd one: x=7\sqrt{3}
4th one: x=4\sqrt{2}

Answer 2

`\sin 45 = (5√(2))/(c)\\ (1)/(√(2))=(5√(2))/(c)\\c=5√(2)*√(2) = 5*2 = 10\\ \\ \\x^2 + x^2 = 8^2\\2x^2=64\\x^2 = 32\\x=√(32)=4√(2)\\ \\ \\ \sin60=(x)/(14)\\ (√(3))/(2)=(x)/(14)\\2x=14√(3)\\x=7√(3)\\ \\ \\ \tan60=(4√(6))/(x)\\ √(3)=(4√(6))/(x)\\x√(3)=4√(6)\\x=(4√(6))/(√(3))=(4√(18))/(3)=4√(2)`
