Answer:

Step-by-step explanation:

The angles that you have shown are called same side exterior angles.

All same side exterior angles add to 180 degrees

Since we know this, we can make the following equation:

2y+2+4y-2=180

6y=180

y=30

To get each angle you can plug in y:

2*30+2=62

4*30-2=118

I hope this helps :)

Answer:

x = 5/33 or 0.151515151

Step-by-step explanation:

7(-6x-2) = 8(3x-4)

step 1: simplify the equation.

-42x - 14 = 24x - 4

step 2: isolate the variable (using the balance method).

-42x - 14 + 14 = 24x - 4 + 14

-42x = 24x + 10

-42x - 24x = 24x - 24x + 10

-66x = 10

step 3: solve for x.

x = 10 ÷ -66

x = 5/33

The base of a right circular cylinder has a diameter of 5.00 inches. Sally measured the circumference of the base cylinder and r
LUCKY_DIMON [66]

Answer:

The percent of error in her measurement is 1.3%

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter

we have

D=5\ in

assume

\pi=3.14

substitute

C=(3.14)(5)=15.7\ in ----> This value represent the 100% (theoretical value)

Find the difference between the theoretical value and the measured value

15.7-15.5=0.2\ in

Find the percentage by proportion

15.7/100=0.2/x\\ x=100*0.2/15.7\\ x=1.3\%
