Answer:

\displaystyle 8,1

Step-by-step explanation:

Use the Pythagorean Theorem twise [first time for the <em>reflexive </em><em>edge</em> and the second time for the <em>longer leg</em> of the other triangle]:

\displaystyle a^2 + b^2 = c^2 \\ \\ a^2 + 5^2 = 10^2 \hookrightarrow 100 = 25 + a^2 \hookrightarrow \sqrt{75} = \sqrt{x^2}; 5\sqrt{3}\:[or\:8,6602540378...] = a \\ \\ \\ \\ a^2 + b^2 = c^2 \\ \\ x^2 + 3^2 = 5\sqrt{3}^2 \hookrightarrow 75 = 9 + x^2 \hookrightarrow \sqrt{66} = \sqrt{x^2}; \sqrt{66}\:[or\:8,1240384046...] = x \\ \\ \boxed{\boxed{8,1 \approx x}}

Help me please<br>I want the step by step explanation!!​
DiKsa [7]

Answer: AB=√17, AD=√98,6

Step-by-step explanation:

AB²=BC²+AC²-2*BC*AC*cosACB

AB²=5²+4²-2*5*4*0,6=25+16-24=17

AB=√17

AD²=AC²+CD²-2*AC*CD*cosACD

cosACD=cos(180°-ACB)=-cosACB

AD²=4²+7²-2*4*7*(-0,6)=16+49+33,6=98,6

AD=√98,6
