Answer:
x=74 degrees
Step-by-step explanation:
Make a right triangle with the angle x in the bottom left of it. You then know that one angle is 90 degree. To find the top angle, do 106-90 to find the top angle, sense the angle in the created triangle to the angle inside + the 90 degrees the long side of the triangle creates. Then you know that two angles are 90 and 16 degrees. Then 90 + 16 + x = 180. So 106 + x = 180. Then by subtracting 106, you find that x must equal 74. This is the angle x in the shape given.
24 hours in a day* 14 days in two weeks= 336 hours total
Final answer: 336 hours

If the sum of the digits is exactly divisible by 3 then the actual number is also exactly divisible by 3
→

so we will divide both top and bottom by 3 to simplify the fraction.

Negative version works the same exact way but with a negative sign
Now get the square root of 30
