ABCD is a rectangle.Diagonal AD=10 and AB=8. What is the perimeter of the rectangle? *

1 answer:

8 0

Perimeter is going to be all sides added up. Because it’s a rectangle we know that side AD is the same as the opposite parallel side, which would be BC. And AB is the same as CD. Therefore 10+10+8+8
Answer : A. 36

Please help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

dexar [7]

Only raul has correctly identified a base and corresponding height..... the remaining haven't.....
in the case of mark he's incorrect because any side can be the base but what matters is that the base must always be perpendicular to the height
in kiki's case... she's wrong because what she identified is the slant height... not height

How do I rotate a point by 180 degrees clockwise?

gizmo_the_mogwai [7]

180 degrees is half of a circle, and clockwise means turning in the direction a clock does - right.

So a point would be turned right halfway around.

A 12-foot ladder leans against the wall; the base of the ladder is 2 feet away from the wall.To the nearest tenth of a foot, how

ludmilkaskok [199]

<h3>The ladder will reach a height of 11.8 feet up the wall</h3>

<em><u>Solution:</u></em>

The ladder, wall and base of the ladder from wall forms a right angled triangle

Length of ladder forms the hypotenuse

Length of ladder = 12 foot

base of the ladder from wall = 2 feet

<em><u>To find: height of wall</u></em>

By pythagoras theorem.

$c^2 = a^2+b^2$

Where,

"c" is the Length of ladder

"a" is the base of the ladder from wall

"b" is the height of wall

Substituting the values,

$12^2 = 2^2+b^2\\\\144 = 4 + b^2\\\\b^2 = 140\\\\b = \pm 11.832 \\\\Ignore\ negative\ value\\\\b \approx 11.8$

Thus, the ladder will reach a height of 11.8 feet on wall
