SA= 2(l x w) |+2(l x h)+2(h x w)

= 2(14 x 12.4) +2(14 x 1)+2(1x 12.4)

=2(173.6)+2(14)+2(12.4)

=347.2|+28+24.8

Of the following points, name all that lie on the same horizontal line

lina2011 [118]

Answer:

(-5,7) (5,-7)

Step-by-step explanation:

When you are told to lable, show or name the points that lie on a horizontal line, it basically means that; when a line is drawn, it passes through the selected points without changing the direction when joined together (horizontally).

From the above problem, (-5,7) and (5,-7) lie in the same horizontal line.

For (7,-5) and (-7,5) lie in the same vertical line.

Thereforeour, the answer is (-5,7) (5,-7).

Here's a diagram showing how to combine angles LDA (in red) and angle ADE (in blue). Hopefully it becomes a bit clearer why these two angles add up to line segment LE. Erase the shared segment DA if it helps show LE better.
