∠XFG is an interior angle of ΔEFG.

∠EFG is an interior angle of ΔEFG.

∠FEZ is an exterior angle of ΔEFG.

∠YGE is an exterior angle of ΔEFG.

∠EGF and ∠FGY are supplementary angles.

∠FEG and ∠FGE are supplementary angles.

Answers 2, 3, and 5 are the right answers.

Answer: The explanation that whether given statement are correct or not is mentioned below.

Step-by-step explanation:

Linear angles are complementary.

Linear angles are complementary is incorrect.

Because, the sum of linear angles is always supplementary(180°).

And, two angles are called complementary if there sum is 90°.

Corresponding angles are congruent is not correct always.

Since it is possible if they are made on parallel lines by the same transversal.

Alternate interior angles are supplementary is not correct always.

Because, Alternate interior angles are formed when a transversal passes through two lines.

Their sum is only supplementary if they are made by perpendicular transversal on parallel lines.

Alternate exterior angles are linear is not correct.

Because, their sum is not equal to 180°.

And, Their sum is only supplementary if they are made by perpendicular transversal on parallel lines.

Vertical angles are supplementary is not correct.

Because, their sum is not equal to 180°.

The sum of the angles of a triangle is 180 degrees is correct.

Because the sum of all interior angles of a polygon is n(n-2)×180° and for Δ, n=3.

Same side interior angles are complementary is not always correct.

If they are made on the parallel lines by the same transversal then their sum is supplementary.

Linear angles are adjacent is correct.

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.

Vertical angles are adjacent is not correct.

Because Vertical Angles are the angles opposite each other when two lines cross.

Chandresh is helping his father paint the fence in their back yard. The fence is represented by the shaded part of the diagram b

Lyrx [107]

B. The total area painted is 864; they must buy two cans of paint.

Step-by-step explanation:

Step 1:

A rectangle's area can be calculated by multiplying its length and its width. The wall is made up of 5 different types of rectangular walls. All walls are 8 feet tall but the length varies.

Step 2:

The area of the 20 feet long wall = $(length)(width)= (20)(8) =160,$

The area of the 10 feet long wall = $(length)(width)= (10)(8) =80,$

The area of the 5 feet long wall = $(length)(width)= (5)(8) =40,$

The area of the 4 feet long wall = $(length)(width)= (4)(8) =32,$

The area of the 15 feet long wall = $(length)(width)= (15)(8) =120.$

The area of all the walls = 432 square feet.

Since there are two sides for every wall, total area = $432(2)=864$ square feet.

Step 3:

If one paint can covers 500 square feet,

the number of cans required to paint 864 square feet = $\frac{864}{500} = 1.728$ cans.

so 2 paint cans are needed to paint 864 square feet which is option B.

An urn contains six chips, numbered 1 through 6. two are chosen at random and their numbers are added together. what is the prob

vitfil [10]

<span>2/15 if drawn without replacement. 1/9 if drawn with replacement. Assuming that the chips are drawn without replacement, there are 6 * 5 different possibilities. And that's a low enough number to exhaustively enumerate them. So they are: 1,2 : 1,3 : 1,4 : 1,5 : 1,6 2,1 : 2,3 : 2,4 : 2,5 : 2,6 3,1 : 3,2 : 3.4 : 3,5 : 3,6 4,1 : 4,2 : 4.3 : 4,5 : 4,6 5,1 : 5,2 : 5.3 : 5,4 : 5,6 6,1 : 6,2 : 6.3 : 6,4 : 6,5 Of the above 30 possible draws, there are 4 that add up to 5. So the probability is 4/30 = 2/15 If the draw is done with replacement, then there are 36 possible draws. Once again, small enough to exhaustively list, they are: 1,1 : 1,2 : 1,3 : 1,4 : 1,5 : 1,6 2,1 : 2,2 : 2,3 : 2,4 : 2,5 : 2,6 3,1 : 3,2 : 3,3 : 3.4 : 3,5 : 3,6 4,1 : 4,2 : 4.3 : 4,4 : 4,5 : 4,6 5,1 : 5,2 : 5.3 : 5,4 : 5,5 : 5,6 6,1 : 6,2 : 6.3 : 6,4 : 6,5 : 6,6 And of the above 36 possibilities, exactly 4 add up to 5. So you have 4/36 = 1/9</span>

A painting crew reported that a job is 3/5 completed what is the fraction of the job remains to be done

HACTEHA [7]

Hi!

<h3>So we need to subtract 3/5 from a whole fraction. (5/5)</h3>

$\frac{5}{5}-\frac{3}{5}=-\frac{2}{5}$
