Answer:

1.9 mm

Step-by-step explanation:

Circumference of circle = 2πr

             2πr = 12.1 mm

     \sf 2* \dfrac{22}{7}*r= 12.1\\\\

                  \sf r = \dfrac{12.1*7}{2*22}\\\\

                     = 1.925

                 \sf \boxed{radius =1.9 \ mm }

Determine whether each of the following pairs of angles have equal measures.
Hatshy [7]

The pairs of angles that  have equal measures are:

  • LJP
  • NJR
  • MJP
  • PJR

The pairs of angles that do not  have equal measures are:

  • MJK
  • PJR
  • KJR
  • MJP
  • KJL
  • LJM

<h3>What is an angle?</h3>

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

It is given that:

Both MJK and  PJR can be seen as (Unequal angles)

The angle MJK  is ( 90 degrees), then  angle PJR will be ( 48 + 46 )= 94 degrees

Both LJP and NJR  can be seen as ( Equal angles)

The measure of angle LJP = 48 + 46 + 48 = 142 degrees

The measure of angle NJR = 48 + 48 + 46 = 142 degrees

KJR & MJP = Unequal

The angle KJR will now be [ 360 - (46+48+48+46+90) ]

= 82 degrees

The  angle MJP  will be ( 94 degrees)

Both KJL & LJM  are Unequal, then

The angle KJL  will be  42 degrees, then angle LJM  will be ( 90 - 42 )

= 48 degrees

One angle is eight times it’s supplement increased by 45 degrees. What is the measures of the two supplementary angles?
Nastasia [14]
Angle 1 = 8x + 45
Angle 2 = x

x + 8x  + 45 = 180
combine like terms

9x + 45 = 180
subtract 45 from both sides

9x = 135
divide both sides by 9 to isolate x

x = 15

Angle 1 = 8(15) + 45 = 165 degrees
Angle 2 = 15 degrees

Sindrei [870]

Answer:

Step-by-step explanation:

a = 35 feet

b = 54 feet

h = 28 feet

Area=\frac{[a+b]*h}{2}\\\\=\frac{[35+54]*28}{2}\\\\=\frac{89*28}{2}\\\\=89*14\\\\

= 1246 square feet
