If you look from the points at angle 73, to 42, to 131, to z, the shape makes a quadrilateral.
Since the total of the interior angles in a quadrilateral add up to 360 you make an equation:
360 = 131 + 73 + 42 + 7 + x
Re-arrange the equation to get the x alone, by subtracting:
360 - 131 - 73 - 42 = x
114 = x
So x = 114 degrees<span />
Answer:
28.26
Step-by-step explanation:
The question gives the first three digits of π, which is 3.14, and it gives us the radius, which is 3. So, just substitute them into the formula and you’ll get 3.14(3^2). Solve it and the final answer is 28.26.
Hope this helps! :)
Answer:
your answer is correct.. its 10
Step-by-step explanation:
- you got to look at the length of each line
- observe the distance between each letter and calculate your answer
as you can see the line DC and EF are the same exact length.
CM =5
line CM is half of line DC. which means to fine the length of EF you must multiply 5 by 2 (5×2) to get the length of EF which is 10
hope this helps
