Answer:
A = [tex]\frac{5\pi }{6}[/tex]
Step-by-step explanation:
Given that Cos A = [tex]-\frac{\sqrt{3} }{2}[/tex]
cos A = [tex]cos (\pi -\frac{\pi }{6} )[/tex]
A = [tex]\pi - \frac{\pi }{6}[/tex]
A = [tex]\frac{5\pi }{6}[/tex]

2/3x-7=11
Pls help
Answer:
x = 27
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] x - 7 = 11 ( multiply through by 3 to clear the fraction )
2x - 21 = 33 ( add 21 to both sides )
2x = 54 ( divide both sides by 2 )
x = 27
The value of x in the equation 2/3x-7 =1 is 12.
The given equation is 2/3x-7 =1.
x is the variable in the equation.
Minus is the operator.
To solve for x add 7 on both sides:
2/3x-7+7=1+7
2/3x=8
Multiply both sides by 3/2.
x=3/2×8
x=12
Hence, the value of x in the equation is 12.

Answer:
D or 176.71 inches squared.
Step-by-step explanation:
the radius is 7.5. put it in a calculator and you get D.
Answer:
[tex]176.7 in^{2}[/tex]
Step-by-step explanation:
The area of a circle is defined as:
[tex]A = \pi r^{2}[/tex]
Where r is the radius and A is the area. We're given the diameter, 15 inches. The radius is half of the diameter, so the radius is therefore 7.5 inches. Now let's take this value back into the formula above:
[tex]A = \pi r^{2} =\pi (7.5)^{2} = 56.25\pi = 176.7 in^{2}[/tex]
So the circle has an area of [tex]176.7 in^{2}[/tex]
Hope this helps!

Which type of transformation maps trapezoid PQRS onto trapezoid P'Q'R'S'? reflection rotation translation dilation
Answer:
Dilation.
Step-by-step explanation:
From the given picture , it can be seen that the size of trapezoid P'Q'R'S' is decreased from trapezoid PQRS .
Reflection , rotation and translation are rigid motions that produces congruent images and do not change the size of the shapes.
But dilation is not a rigid motion because it changes the size of the shape by using a scale factor.
Hence, the transformation maps trapezoid PQRS onto trapezoid P'Q'R'S' is "Dilation".
Answer: D) dilation
