Answer:
x = y · 11
Step-by-step explanation:
Since x is divided by 4, we have to multiply each side by 4.
x-7=y · 4 To get x by itself, add 7 to each side to get x = y · 11
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
