Question

What us the length of PQ to the nearest tenth. hint use distance formula or pythagorean theorem

Answer 1

ok

length of side 1 = 6

short leg = 4

Pythagorean theorem

`\begin{gathered} PQ\text{ = }\sqrt[]{(6)^2+(4)^2} \\ PQ\text{ = }\sqrt[]{36\text{ + 16}} \\ PQ\text{ = }\sqrt[]{52} \end{gathered}`

Using the distance formula

`\begin{gathered} PQ\text{ = }\sqrt[]{(7-1)^2+(2-6)^2} \\ PQ\text{ = }\sqrt[]{6^2+4^2} \\ PQ\text{ = }\sqrt[]{36\text{ + 16}} \\ PQ\text{ = }\sqrt[]{52} \end{gathered}`
