Step-by-step explanation:
To find the length of the rectangle we solve the PLA triangle
Using the Pythagorean theorem we find the PL side.
Then the length of the rectangle is 12.65
Now we solve the MALU triangle. Where MU = PL
We use the Pythagorean theorem:
Where LU and MA are unknown.
Finally we solve the triangle MPA
Where PM = LU
So:
Now we have two equations and two unknowns. So we solve the system.
(i)
We introduce (ii) in (i)
Now we clear MA
MA = 1.3342 (iii)
Now we introduce (iii) in (ii)
1.3342^2 + 4^2 = LU^2
LU = 4.2166
Now we have the length of the rectangle and also its width.
The area A of a rectangle is:
A = l*w
Where
l = length
w = width
A = 4.2166*12.65
A = 53.34![units^2](/tpl/images/0021/8720/9ed84.png)
Ответ:
1. let r be the point with unknown x-coordinate. consider vectors
and ![\overrightarrow{rs}=(2-x).](/tex.php?f=\overrightarrow{rs}=(2-x).)
these vectors are colinear and
then
2. if you need correct formula, then
answer: point r partitions the directed line segment from q to s in a m: n, the ratio to determine point r is
