Answer:

\huge\boxed{x=54^o}

Step-by-step explanation:

<em>Look at the picture.</em>

<em />

We have:

l=108^o

Therefore

2\alpha=108^o           <em>divide both sides by 2</em>

\dfrac{2\alpha}{2}=\dfrac{108^o}{2}\\\\\alpha=54^o

Barb is going to cover a rectangle area 8 feet by 10 feet with rectangle paving blocks that are 4 inches by 8 inches by 2 inches
soldier1979 [14.2K]

Step-by-step explanation:

First, transform 8 feet and 10 feet into inches so we can work with the same measurements

8 * 12 = 96 in

10 * 12 = 120 in

Next find the patio rectangle area.

96 * 120 = 11520 in^2

Now find the paving block area

4 * 8 = 32 in^2

Now, find out how many paving blocks will go into the patio rectangle area.

11520 / 32 = 360

The minimum number is 360 paving blocks

What is the slope of all lines parallel to the line 4x-5y+-1?
Bond [772]

Given equation of the line ,

\implies 4x - 5y +(-1) = 0

Simplify ,

\implies 4x - 5y - 1 = 0

Transpose terms to RHS ,

\implies 5y = 4x - 1

Divide both sides by 5 ,

\implies \boxed{ y =\dfrac{4}{5}x -\dfrac{1}{5}}

Now we know the slope intercept form of the line as y = mx + c we have ,

  • m =\dfrac{4}{5}

As we know that the slope of all parallel lines are same . Henceforth ,

  • m_{|| \ lines } =\dfrac{4}{5}
