Answer:

IT is 41.5 heres the steps

Step-by-step explanation:

first step 21 divided by 2 = 10.5

Then you do 10.5 + 1 = 11.5  

then you do 11.5 times 5 =  57.5

Then 2 times 2 times 2 times 2= 16

then 16 - 57.5 = 41.5 is your answer

Firlakuza [10]

Answer: 19 degrees

Step-by-step explanation:

<FOE is the central angle of an arc of 52 degrees and is thus 52 degrees.  Then by supplementary angles <COD is 71 degrees and angle BOA is thus also 71 degrees.  Then by supplementary angles <BOC is 19 degrees and arc BC is thus also 19 degrees.

8) Find m 5x + 5 11x + 15
Misha Larkins [42]

Answer:

 15 • (4x + 11)

 ———————

         11      

Step-by-step explanation:

Step  1  :

            5

Simplify   ——

           11

Equation at the end of step  1  :

          5          

 (5x +  (—— • x)) +  15

         11          

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  11  as the denominator :

          5x     5x • 11

    5x =  ——  =  ———————

          1        11  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

5x • 11 + 5x     60x

————————————  =  ———

     11          11

Equation at the end of step  2  :

 60x    

 ——— +  15

 11    

Step  3  :

Rewriting the whole as an Equivalent Fraction :

3.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  11  as the denominator :

         15     15 • 11

   15 =  ——  =  ———————

         1        11  

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

60x + 15 • 11     60x + 165

—————————————  =  —————————

     11              11    

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  60x + 165  =   15 • (4x + 11)

Final result :

 15 • (4x + 11)

 ——————————————

       11

I NEED HELP WITH THIS one angle of a triangle measured 145 degrees. The other two angles are in a ratio of 2:3. what are the mea
hjlf

Answer:

Step-by-step explanation:

A triangle has 180 degrees in total. One of the angles are 145 degrees, so we can subtract and get 35 degrees. Then, it says that the remaining angles are in a ratio 2:3. So, we would have:

2x:3x = 35 \\2x+3x = 35\\5x=35\\x=7

Now that we know what x is, we can multiply that to our ratio:

2\cdot7=14 \text{ degrees for the first angle}\\3\cdot7=21 \text{ degrees for the second angle }
