2.37t = feet, where t is time, in minutes. for 6 minutes we do 2.37(6) = 14.22 feet
Answer:
x = 10
Step-by-step explanation:
Since two angles lie on line M, we know that their sum will be equal to 180. Since we know one the their angles, we subtract 136 from 180 and get 44.
We also know that the sum of all a triangle interior angle together equal 180. We all ready have two of those angles so we can now find the third.
44 plus 90 equals 134.
180 minus 134 equals 46. So now we know the measurement of the last angle.
Now to we have to solve for x.
We know that 4x+6 equal 46, since they both represent the angle of angle L.
Once you solve 4x+6=46, you will get x = 10.
Answer: x = 10
