Find the total ° of the shape.
(5-2) x 180°= 540°

x+21°+x = 540°-105°-154°-88°
2x+21° = 193°
2x = 193°-21°
2x = 172°
x = 172° ÷ 2
x = 86°

Answer:

86

Step-by-step explanation:

First we need to know that a hexagon contains 540 degrees worth of angles.

Now we can build an equation:

x + 21 + 105 + x + 154 + 88 = 540

Now we gather like terms:

2x + 368 = 540

Subtract 368 from both sides of the equation:

2x + 368 -368 = 540 -368

2x = 172

Now we divide both sides by 2 to isolate the x:

\frac{x}{2}  = \frac{172}{2}

x = 86

0.04 with 4 repeating as a fraction. Not the 04 repeating just the 4 is repeating. What is the answer???
Dmitriy789 [7]

Answer:

2/45

Step-by-step explanation:

0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as: (\frac{1}{10} )(\frac{4}{9} ). Multiplying the two fractions results in 4/90 which can be simplified to 2/45.

What is, 7 3/10+6 1/3+2 7/10?
snow_lady [41]

7 3/10 + 6 1/3 + 2 7/10

First change them to improper fractions

73/10 + 19/3 + 27/10

now find the common denominator which would be 30

73/10 = 219 /30

19/3 =   190/30

27/10 =  81 /30

now add (219 + 190 + 81) = 490/30

now divide 490 ÷ 30 = 16 1/3

Your answer is 16 1/3

Hope this helps. :)
