Answer:

Angle A is 59.5 degrees

Step-by-step explanation:

i got you!

Answer:

∠ A ≈ 59.5°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{56}{65}[/tex], then

A = [tex]sin^{-1}[/tex] ( [tex]\frac{56}{65}[/tex] ) ≈ 59.5° ( to 1 dec. place )

Formulas:

A= πr²

d= 2r

Solving:

A=14πd²=14·π·6²≈28.27433ft²

Answer:

[tex]18r+\frac{1}{2}(14)(r)=182[/tex]

Step-by-step explanation:

Area of the composite figure ABCDE = Area of triangle ABE + Area of the rectangle BCDE

Area of triangle ABE = [tex]\frac{1}{2}(32-18)(r)[/tex]

                                  = [tex]\frac{1}{2}(14)(r)[/tex]

Area of rectangle BCDE = 18 × r

                                        = 18r

Total Area = [tex]\frac{1}{2}(14)r+18r[/tex]

Therefore, equation to get the value of 'r' will be,

[tex]18r+\frac{1}{2}(14)(r)=182[/tex]

The value of x is approximately (7√3) / 3.

Given that a right triangle with base = x and the perpendicular side = 7 and the reference angle is 60°, we need to find the value of x.

To find the value of x in a right triangle with a base of x and a perpendicular side of 7, and with a reference angle of 60 degrees, we can use the tangent function.

The tangent of an angle is defined as the ratio of the length of the side opposite the angle (in this case, 7) to the length of the side adjacent to the angle (in this case, x). So we have:

tan(60°) = 7 / x

Now, we can solve for x by multiplying both sides of the equation by x:

xtan(60°) = 7

To find the value of x, we need to know the value of tan(60°). The tangent of 60 degrees is √3. So we have:

x√3 = 7

To isolate x, we divide both sides of the equation by √3:

x = 7 / √3

To simplify the expression, we multiply both the numerator and the denominator by √3:

x = (7 / √3)(√3 / √3)

= (7√3) / 3

Therefore, the value of x is approximately (7√3) / 3.

Answer:

 IS a parallelogram

Step-by-step explanation:

The slope formula for the slope of the line between points (x1, y1) and (x2, y2) is ...

  m = (y2 -y1)/(x2 -x1)

The distance formula for the length of that same line is ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

Here, you're asked to use each of these formulas 4 times, once for each side of the quadrilateral. I find it convenient to let a calculator or spreadsheet do the repetitive calculations. The result is attached.

The attachment shows that opposites sides have the same length and slope, so are parallel. The quadrilateral is a parallelogram. (The two points used in each calculation are the ones on the result line and the line immediately below. That is why point B is copied to the end of the list.)

_____

Additional comments

There are much simpler ways to prove the figure is a parallelogram. My favorite is to add the coordinates of the end points of the diagonals:

  B +D = (-2+6, -9-3) = (4, -12)

  C +E = (0+4, -5-7) = (4, -12)

These values being the same demonstrates the midpoints of the diagonals are coincident. That will only be the case if the quadrilateral is a parallelogram.

__

If you must use slope and distance formulas, showing either pair of opposite sides is parallel and have the same length is sufficient to guarantee that the other two sides are also parallel and have the same length. That is, the calculations required in this problem only need to be applied to one pair of opposite sides. (Using a spreadsheet, it's not a lot of extra work to do the calculations for both pairs of opposite sides.)

Answer:

x = 20

Step-by-step explanation:

Each line creates a 180° angle on each side of it. Since these lines intersect, they have congruent angles. This means that these two quantities can be set equal to each other.

3x + 50 = 6x - 10

Solve by combining like-terms and isolating x. Move the 3x to the right by subtracting it from both sides.

50 = 3x - 10

Move the 10 to the left by adding it to both sides.

60 = 3x

Divide the 3 from both sides to isolate the x.

x = 20

Furthermore, this can be checked by plugging in 20 to x and seeing if the expression is true.

3(20) + 50 = 6(20) - 10

Answer:

x = 7

y = -3

Step-by-step explanation:

the first equation is already solved for 'y' so we can substitute '-2x+11' for 'y' in second equation

3x + (-2x + 11) = 18

x + 11 = 18

x = 7

solve for 'y'

y = -2(7) + 11

y = -14 + 11

y = -3
