i tried on a calculator and it gave me 211.125
Answer:
x = 15
Step-by-step explanation:
There are 2 triangles. The small triangle CDE has sides that are 8 and 20.
The big triangle CAB has sides 6+8 and 20 + x. Add the 6 and 8 which is 14. Create a proportion and cross multiply, divide, then solve for x.
Answer:
The surface area is 
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces.
so
![SA=b^{2}+4[\frac{1}{2}(b)(l)]](https://tex.z-dn.net/?f=SA%3Db%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28l%29%5D)
we have
substitute the values
![SA=0.4^{2}+4[\frac{1}{2}(0.4)(0.6)]=0.64\ m^{2}](https://tex.z-dn.net/?f=SA%3D0.4%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7D%280.4%29%280.6%29%5D%3D0.64%5C%20m%5E%7B2%7D)
The lengths of the two segments below then tell whether they are congruent
YZ = 4
XW = 12
not congruent
This is further explained below.
<h3>What is a number line?</h3>
Generally, A number line is a depiction of a graded straight line that serves as an abstraction for real numbers, which are symbolized by the
Number lines are used in introductory mathematics. It is generally accepted that a real number may be assigned to each point on a number line and that each point can be assigned to a real number.
YZ = Z - Y = 1 -(-3) = 4
XW = W -X = 5 -(-7) = 12
Because the segments are not the same length, they cannot be considered congruent.
In conclusion, It is self-evident that segment YZ will not have the same length as segment XW since it is just a portion of the latter.
