inessss [21]

Step-by-step explanation:

\underline{ \underline{ \text{Given}}} :

  • Length of MN ( Base ) = 8
  • Length of NL ( Hypotenuse ) = 10

\underline{ \underline{ \text{To \: find}}} :

  • Length of LM ( Perpendicular )

\underline{ \underline{ \text{Using \: pythagoras \: theorem}}} :

\boxed{ \sf{ {Hypotenuse}^{2}  =  {Perpendicular}^{2}  +  {Base}^{2} }}

⤑ \sf{  Perpendicular =  \sqrt{ {(Hypotenuse)}^{2}  -   {(Base)}^{2}  } }

⤑ \sf{ \sqrt{ {(10)}^{2}  -   {(8)}^{2}  } }

⤑ \sf{ \sqrt{100  -  64}}

⤑ \sf{ \sqrt{36}}

⤑ \boxed{ \sf{6\: units}}

Isabella has a board that is 5.24 feet long and 1.34 feet wide. ​
Masteriza [31]

Answer:

<u>Length of 1 piece= Length of total divided by 8</u>

Step-by-step explanation:

Length of total= 5.24 feet long

Width of total= 1.34 feet wide

Width is divided by 1 line so, there are 2 parts.

Width= 1.34 divided by 2

Width= 0.67 feet wide

Length is divided by 7 lines, so there are 8 parts.

Length= 5.24 divided by 8

Length=0.655 feet long

They are asking for formula to find the length of each piece

<u>Length of 1 piece= Length of total divided by 8</u>

<u></u>

Hope that helps!
