Answer:
All you do is find each triangle
Step-by-step explanation:
- if I am correct it is 70 ×
![110 \div 2](https://tex.z-dn.net/?f=110%20%5Cdiv%202)
- do this 2 times and find y
That would be the one and only 22
Given:
The figure of a right angle triangle.
A line segment intersect the two sides and parallel to third side of the triangle
To find:
The value of x.
Solution:
According to basic proportionality theorem, if a line segment intersect the two sides and parallel to third side of the triangle, then it divides the two sides proportionally.
Using basic proportionality theorem, we get
![\dfrac{8}{20-8}=\dfrac{6}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7B8%7D%7B20-8%7D%3D%5Cdfrac%7B6%7D%7Bx%7D)
![\dfrac{8}{12}=\dfrac{6}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7B8%7D%7B12%7D%3D%5Cdfrac%7B6%7D%7Bx%7D)
![\dfrac{2}{3}=\dfrac{6}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B3%7D%3D%5Cdfrac%7B6%7D%7Bx%7D)
On cross multiplication, we get
![2\times x=6\times 3](https://tex.z-dn.net/?f=2%5Ctimes%20x%3D6%5Ctimes%203)
![2x=18](https://tex.z-dn.net/?f=2x%3D18)
![x=\dfrac{18}{2}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B18%7D%7B2%7D)
![x=9](https://tex.z-dn.net/?f=x%3D9)
Therefore, the value of x is 9.
34.76
o
, nearly.
Explanation:
Angle of elevation = arc tan( (vertical height)/(length os the shadow)).
Here, this angle is
arc tan (12.5
/
18) =
34.78
o
, nearly
I'm a little confused by this. 1/2 is too big, but 1 1/2 is too small?
