We are given the length of AC and AB to be 20 and 6, respectively, so we can subtract 6 from 20 to find BC to be 14 cm.
The circumference of a circle is equal to


The answer is approximately 87.96 cm
He watches TV at around 8:00 P.M., though it could be any other time around the world.



<u>By first equation,</u>


<u>Now, we can find the original value of y.</u>








<u>Now, we can find the original value of x.</u>




Therefore, the values of x and y are 5 and 2 respectively.
Step 1) Add up the three given angles: 125+109+83 = 317
Step 2) Subtract the result (found in step one) from 360
360 - 317 = 43
The reason for the 360 is because for any four-sided polygon, the angles always add up to 360 degrees.
The answer is 43
19 can be equal to 19 and it should turn out to be as a whole number which is 1
