The surface area is 169.65ft^2
It's 10.4 because you divide 272.48 by 26.2 and get 10.4
<span>According to the figure, the two lenghts AE and EC are congruents, and so are AE and ED.Besides the two lines AB and DC are parallels, consequently angle A and C are congruent (interior Alternate angles). All this statements tell that triangle ABE and Triangle DEC congruent by the Side Angle Side Postulate, so the true answer is B.) Triangle AEB and Triangle CED</span>
Hint : The product of the slopes of two lines perpendicular to each other is - 1 .
______________________________
In slope-intercept ( y = ax + b ) from of the linear equations the coefficient of x is the slope of the line.
Thus :
Slope of line a = - 14
______________________________
Suppose that the slope of line b is x according to the Hint we have :
- 14 × x = - 1
negatives simplify
14x = 1
Divide both side by 14
14x ÷ 14 = 1 ÷ 14
x = 1/14
So the slope of line b is 1/14
_____________________________
Now let's find the equation of line b by point-slope formula using the point question have us ( 2 , 6 ) :
y - y( given point ) = Slope × ( x - x ( g p ) )
y - 6 = 1/14 × ( x - 2 )
y - 6 = 1/14 x - 2/14
y - 6 = 1/14 x - 1/7
Add both sides 6
y - 6 + 6 = 1/14 x - 1/7 + 6
y = 1/14 x - 1/7 + 42/7
y = 1/14 x + 41/7
And we're done ...
