Christie needs 54.3 Square feet of laminate wood suppose each square foot of laminated wood cost $.60 find the amount she has to
Irina18 [472]
It will cost $33.

Since wood cost $ .60 sq ft, you can assume she needs to buy 55 sq ft because she will need to buy enough to have 54.3 square ft.

55 x $ .60 = $33

$32.58 would be he total for the 54.3 sq ft and .42 cents would be for the left over .7 sq ft that she didn’t use

In circle A, ∠BAE ≅ ∠DAE.
kirza4 [7]

The image of circle A is missing, so i have attached it;

Answer:

x = 17

Step-by-step explanation:

In Δs EAB and EAD

We are told that;

∠BAE ≅ ∠DAE

AB = AD = AE

Now,

The Two triangles have two corresponding equal sides and the angles between them are equal, thus, we can say that the two triangles are congruent by SAS (Side Angle Side) postulate of congruence

By using the result of congruence, we can say that;

EB ≅ ED

We are given that;

EB = 3x - 24 and ED = x + 10

Thus,

3x - 24 = x + 10

∴ 3 x - 24 = x + 10

Add 24 to both sides to give;

3x = x + 34

Subtract x from both sides to give;

2x = 34

Divide both sides by 2 to give;

x = 17

100 POINTS PLEASE HELP!!
andrew-mc [135]

Answer:

a)  ∠2 and ∠4 are a linear pair

∠4 = 115°

b)  ∠2 and ∠7 are alternate exterior angles

∠7 = 65°

c) ∠2 and ∠3 are vertical angles

∠3 = 65°

Step-by-step explanation:

Linear pair : a pair of adjacent angles formed when two lines intersect. The two angles of a linear pair are always supplementary (two angles whose measures add up to 180°)

Alternate exterior angles : when two parallel lines are cut by a transversal (a line that intersects two or more other, often parallel, lines), the resulting alternate exterior angles are <u>congruent</u>.

Vertical angles : a pair of opposite angles formed by intersecting lines. Vertical angles are always <u>congruent.</u>

a)  ∠2 and ∠4 are a linear pair

⇒ ∠2 +∠4 = 180

⇒ 65 + ∠4 = 180

⇒ ∠4 = 180 - 65

⇒ ∠4 = 115°

b)  ∠2 and ∠7 are alternate exterior angles

⇒ ∠2 ≅ ∠7

⇒ ∠7 = 65°

c) ∠2 and ∠3 are vertical angles

⇒ ∠2 ≅ ∠3

⇒ ∠3 = 65°
