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 )

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

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

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

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

⤑ $\sf{ \sqrt{100 - 64}}$

⤑ $\sf{ \sqrt{36}}$

⤑ $\boxed{ \sf{6\: units}}$

Six less than the product of 8 and a number equals 5

olga55 [171]

$\huge\boxed{8x-6=5}$

$\huge\boxed{x=\frac{11}{8}}$

Let's start with "the product of $8$ and a number". I will use $x$ to represent the number. $8x$

"Six less than" $-6$

"equals $5$ " $=5$

Now put it all together. $\boxed{8x-6=5}$

Now I will solve for $x$ . Add $6$ on both sides of the equation. $8x=11$

Now, divide both sides of the equation by $8$ . $\boxed{x=\frac{11}{8}}$
