Answer:

  • C. 93°

Step-by-step explanation:

WY  is the diameter.

WX and XY sum to 180° as half the circle.

<u>Central angle is equal to intercepted arc:</u>

  • mXY = m∠XVY = 87°
  • mWX = 180° - mXY = 180° - 87° = 93°

Correct choice is C

Is A ABC similar to DEF? Why or why not?
vova2212 [387]

Answer:

Option(D)

Step-by-step explanation:

Given are the two triangles, that are ABC and DEF, in which AB=8ft, DE=6ft, AC=10ft and DF=7.5ft.

For the two triangles to be similar, it must satisfy the similarity condition that is:

Both the triangles must have congruent angles and the sides should be proportional. Since, two sides of the given triangles are not proportional.Moreover, ∠A=25° and ∠D=24° which are not equal and ∠C=60° and ∠F=61° which are also not equal.

Therefore, Not all the angles are congruent, thus the triangles cannot be similar.

Which of the following is the equation of a line that has a slope of -2 and passes through the
KATRIN_1 [288]

Answer:

B. y = -2x + 8

Step-by-step explanation:

So the slope is the number that comes before the x, and if the slope is -2, that means the number before is -2, and it is.

And to know if it goes through (1, 6), put those numbers into the equation and see if they match up (x is the y-intercept)

6 = -2(1) + x

6 = -2 + x

x = 8

The one with both of these is B, which means B is the answer

musickatia [10]

Answer:

$1467

Step-by-step explanation:

We must convert the first 3 values to yards as so: 5 ft, 4 ft, and 8 inches. We then convert 8 inches to 2/3 feet. multiply 5*4*2/3 to get 13 and 1/3. multiply that by 110, to get 1466 and 2/3. Round it to $1467

HURRY PLEASEEEEE<br><br> The measure of segment AB with a(-4,-9) and B(4, -3) is
solmaris [256]

Answer: 10

Step-by-step explanation:

using d = \sqrt{(x_{1}-x_{2}  )^{2} +(y_{1}- y_{2} )^{2} } when P_{1} =(x_{1} ,y_{1} ) and P_{2} =  (x_{2}, y_{2})

so d = \sqrt{((-4)-4)^{2}+((-9)-(-3))^{2}  }

d = \sqrt{(-4-4)^{2}+(-9+3)^{2}  }

d = \sqrt{(-8)^{2}+(-6)^{2}  }

d = \sqrt{64+36}

d= \sqrt{100}

d = 10

please give me a brainliest answer
