Answer:

  • x = 54
  • angle ACD = 124°

Step-by-step explanation:

The rule is that the exterior angle (ACD) is equal to the sum of the remote interior angles (the two marked angles on the right).

You are expected to use this relation to write and solve an equation.

  exterior angle = angle D + angle B

  (2x +16) = 58 + (x+12)

  2x +16 = x +70

  x + 16 = 70

  x = 54

Then angle ACD is ...

  angle ACD = (2x +16)° = (2·54 +16)°

  angle ACD = 124°

If the diameter of circle a measures half of the diameter of circle b, then the area of circle b is how many times the area of c
Eduardwww [97]
Circle b:

Diameter = x

Radius = \frac{x}{2}

Area = \pi  r^{2} =  \pi ( \frac{x}{2} )^{2} =   \frac{ \pi  x^{2} }{4}

Circle a:

Diameter = \frac{x}{2}

Radius = \frac{x}{2} *  \frac{1}{2} =  \frac{x}{4}

Area = \pi  r^{2} =  \pi  ( \frac{x}{4} )^{2} =  \frac{  \pi x^{2} }{16}

Thus,

Area of circle b to area of circle a

= \frac{ \pi x^{2} }{4} ÷ \frac{ \pi x^{2} }{16}

= \frac{ \pi x^{2} }{4} × \frac{ 16 }{\pi x^{2}}

= 4

Hence, the area of circle b is 4 times the area of circle a.

Cerrena [4.2K]

Answer:

The possible lengths and widths of the prism will be all those positive ordered pairs whose multiplication is equal to

Step-by-step explanation:

we know that

The volume of a rectangular prism is equal to

where

B is the area of the rectangular base

h is the height of the prism

In this problem we have

substitute and solve for B

-----> area of the rectangular base

therefore

The possible lengths and widths of the prism will be all those positive ordered pairs whose multiplication is equal to
