D=√((7-1)^2+(4-3)^2)=√37

Answer:  \sqrt{(7-1)^2+(4-1)^2}

Step-by-step explanation:

Since, by the distance formula,

The distance between two points (x_1,y_1) and (x_2,y_2) is,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Therefore, the distance between EF is,

\sqrt{(7-1)^2+(4-1)^2}

Which is the required expression,

EF=\sqrt{(6)^2+(3)^2}

EF=\sqrt{36+9}

EF=\sqrt{45} \text{ unit}

Geometry help with number 18!
lora16 [44]
BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36
