Answer:

the triangles are not similar. If they were, they would have the same angles.

The interior angles are not congruent. We can rule out choice B and C.

Just because they have one equal angle does not make them similar. We can rule out D.

A is the best answer.

Answer:

Now, △DEF has interior angles with measures y°, 70°, and 20°.

By using angle sum property,

Now, we can say that,

"The two triangles are not similar because x≠y"

As one angle of measure 70 degree is common in both the triangles.

If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.

Therefore, the two triangles are not similar because x is not equal to

Factor to solve: x² + 18x +27 = 8x +3

patriot [66]

Answer: $x=-4$ $or$ $x=-6$

Subtract 8x+3 from both sides

$x^2+18x+27-(8x+3)=8x+3-(8x+3)$

$x2+10x+24=0$

Factor left side of equation

$(x+4)(x+6)=0$

Set factors equal to 0

$x+4=0$ $or$ $x+6=0$

Final Answer: $x=-4$ $or$ $x=-6$

Find the values of x and y.

Mekhanik [1.2K]

Woah I haven’t done this in a while but all sides have to add up to 180 and the top angle is 60 because it’s a 30, 60, 90 triangel.

Write the linear equation that gives the rule for this table.

Zinaida [17]

Answer:

f(x) = -7x + 1

Step-by-step explanation:

Slope intercept form is

y = mx + b

m is slope

b is y-intercept

--------------------------

y decreases by 7 for each increase of 1 in x

slope = -7

to find "b" plug in one of the points and m = -7

using point (3, -20)

y = mx + b

-20 = -7(3) + b

-20 = -21 + b

b = 1

The equation is

f(x) = -7x + 1

A homeowner's backyard is a rectangle with width 18 yards long and length 16 yards long. They plan to put in a square pool with

Ugo [173]

Answer:

Step-by-step explanation:

Given the dimension of the homeowner's backyard to be width 18 yards long and length 16 yards long, the area of the rectangular backyard id expreesed as;

Area of rectangle = Length * Width

Area of the rectangular backyard = 18yards * 16yards

Area of the rectangular backyard = 288yards²

If they plan to put in a square pool with side length 5 yards long in the backyard, the area of the pool = 5yd*5yd = 25yd²

The remaining area that will contain the tiles = Area of the rectangular backyard - area of the pool

The remaining area that will contain the tiles = 288yd² - 25yd² = 263yd²

Note that we cannot determine the amount of tiles they need to buy since we are not given the dimension of each tile to use. The area needed for the tiles for the rest of the backyard is therefore 263yd².

Amount of tiles needed to buy can be expressed as 263/dimension of a tile.
