Answer:
224 im pretty sure
Step-by-step explanation:
area of a triangle= base x height / 2
if we plug the values from the problem into the equation, we get 8 x 10 / 2 which simplifies into 80 / 2, which is 40. because this is a square pyramid, we know it has 4 triangles, so we multiply 40 by 4, which is 160. now, we find the area of the square, which can be found with the equation length x width. since all sides of square are equal, the equation becomes 8 x 8, which is 64. finally, we add the area of the triangles to that of the square, and we get 224. hope this helps!
Answer:
is the equivalent expression as
is equal to
.
Step-by-step explanation:
Considering the expression
![2s+\left(-4s\right)](https://tex.z-dn.net/?f=2s%2B%5Cleft%28-4s%5Cright%29)
As we know that
- Like terms are said to be the terms which hold the same variables raised to the same power.
- For example,
and
are like terms as they contain the same variable
raised to the same power.
Lets solve the expression
![2s+\left(-4s\right)](https://tex.z-dn.net/?f=2s%2B%5Cleft%28-4s%5Cright%29)
![\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a](https://tex.z-dn.net/?f=%5Cmathrm%7BRemove%5C%3Aparentheses%7D%3A%5Cquad%20%5Cleft%28-a%5Cright%29%3D-a)
![2s-4s](https://tex.z-dn.net/?f=2s-4s)
![\mathrm{Add\:similar\:terms:}\:2s-4s=-2s](https://tex.z-dn.net/?f=%5Cmathrm%7BAdd%5C%3Asimilar%5C%3Aterms%3A%7D%5C%3A2s-4s%3D-2s)
![-2s](https://tex.z-dn.net/?f=-2s)
Therefore,
is the equivalent expression as
is equal to
.

90-41 =49
So the answer to x =49 degrees
Complimentary angles are two angles that equal 90 that us why to solve we subtract 41 from 90
